Is this calcium def?

[Mitakoye Oyasin]

These are some pics of a problem that Im thinking is calcium deficency but not sure. I am growing 3 different strains and only the one really seems to have this issue. My medium is pro mix growing in 3 gal containers using humbolt nutes. I started seeing what I thought was a mag def earlier and I watterd with 2 tablespoons per gallon epsom salt and then foliar fed with sea mag and now the issue seems to be calcium to me. Heres some pics. I had an issue getting the right setting for the natural color to show up so I took a couple of pics of same leaf with different settings. Some pics the colors look different that they do in real life is why I mention that. The strain Im having this issue with is The Ultimate fem from dutch passion. I read the one thread I could find on it and I do agree the ammount of phenos is ungodly and in my opinion what makes this strain from seed not worth it, yet also in my opinion if u have the ability to hunt deep for that cherry I'd have to say I found her out of a batch of 20 fems with 19 or those popping healthy. Only two out of the bunch would I consider quality but the one of those two that I picked is a beauty and so frosty over the purple tinted buds that they look pure white. So , I wanna grow her to her ultimate and I have a new batch I just started 2 weeks into flowering showing no deffincienies yet absolutly beauties they are. Id like to completly get this baby down pat so can anyone help me avoid these deficinces that turned up this time. Im still in mid grow so Im still working on this one but Id sure like to do better on the one that just started not to mention I have clones already poted getting ready for another batch so ...any suggestions???

kinda looks like it is. If you have a look at my current grow- sensi star, that's what they looked like in veg with the leaf burning look on the tips of the serrations. did you add dolomite lime to your promix? I know it says that it has it added already but it is not enough for a lot of plants, as I discovered this time round when I forgot to add dolomite when I mixed up the soil for my clones when I potted them. I have been adding 2 T (tablespoons) each time I mix up a gallon pots worth but missed it this time round. Never had deficiency issues til this go at it. Only thing else I might say is have a look at the plants for any sign of bugs, as they can do similar patchy necrotic type spots on the leaves too. Hope this helps, I'm still a noob but I can now identify this problem LOL learn by error. Maybe someone can confirm that for me.

 

[Mitakoye Oyasin]

thanks. I havent used any dolomite, I just use the str8 hp so mabee I will start that on my very next batch. As for bugs that is not the issue there are not any bugs or mites. There was a bit of white powdery mildew on a couple of my other strain(power kush) it seems to be very succeptable and I have been constantly treating foliarly with Actinovate but the powder mildew never showed up on the ultimates which is what the pics are of but they all have been getting the same foliar. I will use the lime next time and see if it helps I am so far not having this issue that bad with my next batch that has been flowering for only 3 weeks now. Another thing is these babys go a good 11-12 weeks.Thanks for ur feedback. B-Kind

2TSP is too much epsom salt per gallon! You are experiencing Calcium lock out. Stop adding the epsom salt and sea mag, and the problem should resolve itself. You never said anything about your PH of the water or runoff...

It might be time to flush your soil to get rid of any salt buildup or excessive nutrients you got in their. I use CAL/MAG you can get it pretty much anywhere and it's better suited for this problem than epsom salts imho.

Is new growth ok, or is it affecting that to?

 

[LeenieBean]

funny my power kush looks like it might have a bit of that too... weird though cause my humidity is really low.

I been wondering a bit about cal/mag myself. How do you use it in your cycle maggot? what do you use with it for nutes?

 

[Mitakoye Oyasin]

I always use sea cal and sea mag as my mag or cal supp but this night I happend to be out and had some epson salt and the bags instructions said to use 1-2 tablespoons per gallon. So anyways I tried that and I was thinking that may have done exactly what u said maggot so I foliar fed them last night with sea cal. As for my ph I checked my medium and it is 6.8 and I ph ballance my nutrient solution every single time I make a mix no lower than 5.6 and no higer than 6.5. I havent checked the runoff solution on this batch but I always when I nutrate or water run enough that it runs a good bit out the bottom str8 to waste. I let the medium dry pretty good but not desert dry before I do it again. The new growth is fine and it started at the bottom fan leaves and moved up only like 2 or 3 leaves per plant affected but the tips on most are brown just about a centimeter or 2 in. I also didnt mention I co2 supplement. My humidity, I just walked out of grow room , was 55%, and the temps usually ride about 88 sometimes as high as 90. Large are and air cooled systems much air circulation. and that temp is at the top of plant at peak light spot. Lights are 1000w and never closer than bout 18 inches sometimes and some places more but never closer than that.

 

[Mitakoye Oyasin]

LeenieBean I read that the powder mold doesnt care about the humidity having to be high because it actualy encases its spore with water somehow and it must just be the power kush , although it is a great plant, is just very succeptible to this particular diesase and it is the only thing I noticed it succeptable to. I say this cause I have great white shark and this ultimate were talking about in the same room and the last grow same thing with the power kush and I was ready for it treating it before it showed and all and that shit just powers right through any neem oil or actinovate I used. But no other strain was touched and they were in the room the whole time with the infected power kush. Its what made me pick the moms I did cause they were all seedlings together and the ones that didnt even get touched and were the best turned into moms. and now there my babys. lol Anyways. Thanks for the feedback peps. B-Kind

 

[stoney917]

i wouldnt brush pm off as just on the power kush u will regret it start treating e erything around it like it has pm cuz it does just cuz u dont see it doesnt mean its not there. pickup some eagle 20 and hit everything u got in veg 2wks in i may even consider using it since ur strain is a 12wker on a 8wk strain it just would not work... ket somone else chime in and say if its safe to use on a 12wk strain 3wks in. i dont wanna scare ya but pm is a horrible disease and can spread easily. i lost bout 20moms do to one clone i didnt fully eradicake. and bout 1lb of nugz in the trash bro. best of luck.

 

[rives]

You might want to check the epsom salt package again. Mine all say 1 teaspoon per gallon.

 

[Mitakoye Oyasin]

Yea stoney thanks for the concern about the pm. I totaly understand and I have ever since I first saw pm on my pk been using actinovate, its a biological fugicide made for treating pm in every single foliar spray I ever use since I first saw the white powdery stuff. I treated my mother and clone room with some neem oil, just one neem oil treatment because I don't like to use the stuff, I will only use it in the veg stage and actualy I don't use it at all, just to me the severity of pm I did use it once foliar in my mother and veg room and then have foliar sprayed at least once a week since with the bilogiacal treatment. And yes I treat all strains even though I havent seen it there yet, I just mentioned that in case mabee that coulda casued those spots even though the pm never showed up on the ultimates just like mabee the biological fighting the stuff and some kinda war zone reaction lol, hell I really don't know . Prolly not, the problem hasn't gotten anyworse since I started a major foliar routine, loaded with actinovate , the biological for safe measures, and I have continued to see the buds swell nightly. I am gonne end my foliar routine now though because they are getting so fat I don't wanna harm them. B-Kind

I think I was a stoner that night I was out of sea mag and noticed a slight defincency starting and somehow I got tablespoons out of it but yea my pack says 1 teaspoon too. So after reading all of ur input , I greatly appreciate and believe that I did indeed lock up the nutrients with an excess of epsom salt, needless to say I have been up all night flushing and I did monitor my runoff water. It started out at 5.4 ph and 1980ppm after a gallon and a half of water with a clearex solution added. After that galon and half I flushed with 2 more gallons and measured run off and it was down to 855 and pots was still draining at it was getting lower every time I checked it. then I stopped and mixed a complete nutrient solution at 6.0 ph and 1540ppm. I nutrated the whole lot with a half gallon of this and at the end of all of this my runoff was down to 455 even after nutrating with 1540ppm, and my ph was 5.7 in my runoff. Im using complete humbolt nutrients line. I also don't think I mentioned yet I am supplementing with co2 at 1500ppm and my temps stay on average at 88 sometimes up to 90 and this is measured at the top of plant level in the light. All 1000 watt air cooled systems. By the way , I loved my chosen power kush mother, awesome plant in all regards except it wouldnt let go of the powder mildew so I let go of her to keep from having a germination factory around for those spores I mean I know they get everywhere but they fester on her. So Im gonna try to include some more pics of my plants taken from farther back so u can see the whole plant instead of just the bad leaves, and a few close ups of the buds. Thanks so much everyone for ur reasponses. I will take more pics in a week or so and see how my handeling of the situation went. On a side note I just got 3 packs of ak47 fems seriouse today and dropped them into a jar of water so I will try to keep good notes. I grew ak47 years ago as my first select from seed for a mother and hydroponicaly. The years before that it was all bag seed and outdoor. I also got a pack of roadrunner. Is this strain any good like potency and apperance and smell??? B-Kind

Plants are continuing to show posotive growth. I had to tie up branches for a while tonight, they got so heavy from sucking up all of the water from the flush and just continuing to swell that the branches were bending until they were, I don't wanna say breaking cause I straieghtend em up and tied em up, but pinched over on a couple of them ya know. Smell is much stronger in the room since the flush as well. Thinkin about hitting them with one last foliar tonight to help them pull on through this rough spot. I really think all of the foliar sprays that I've given them these last couple of weeks ever since I gave them that dose of epsom salt has helped to keep them on pulling and growing even though at the time I didn't realize I had overdone the epsom I did notice the definciencies showing up and I foliar treated evey one I saw mag, cal and k and I also threw in a couple of base nutrient all around foliars thhroughout these last couple of weeks all with the actinovate to combat fugas problems and even though I just flused the powdery mildew seems to have finaly bitten the dust. I constantly removed any foilage that I saw with any trace of it and treated foiliar with the biological fugicide and it finaly seems to have done the trick. B-Kind

looks like text book cal def spotting to me. i feel you can never go wrong with a low an continue dose of calmag +, like at 2.5mill per gal. if you start seeing rust spotting i bump it up to 5mil per gal. every feeding, every rez. when feeding low amounts the cal mag sulf an iron are always their an never seem to build up an cause any lock out issues. unless your feed is higher then the plants consume.

u add co2 an 1000 watters to the mix an the plant is feeding an growing stronger an faster. cal or mag def must likely will appear.

high run offs show the plant is not consuming what your feeding. just eating what they want an leaving what they dont behind.

When you growing in soil theres no garbage man coming to take away the built up nutes. unlike hydro. thats why i feel it always better to under feed your main nutes, an add low continue dossages of trace elements.

in my opinion theres no nute line that can offer a full spectrum of minerals to the plant. some want more an others less.

run the cal mag 2.5 mil per gal next round with you main nute sched. 2.5 per gall in veg an into early flower. day 20 to 45 into flower try to bump it to 5mil per gallon. day 20 to 45 theres alot of action happening, an the plant needs the cal mag an iron. an if your main nutes are in line, an the right ph is set, shit should fly. usually ph 6.0-6.2 when feeding work best i've experienced in soil


another thing, if i flush an all of a sudden see fresh growth bursting, I KNOW i have been feeding to hard prior. lock outs where present.

be an b-safe an best of luck.....

 

[Mitakoye Oyasin]

Thanks for the info gman. I think u nailed it. I had been really pushing the nutes and I had been using the sea cal and sea mag until about a week prior to spotting I stopped using the sea cal then I treated with too much epson to boot and it was the first time I ever used epsom is why I over used it I had ran out of my sea mag they needed a dose and my hydro shops an hour away and I work at night so to the medicine cabniet and epsom and internet I went and somewhere something said two tablespoons and I hit em up. Its good to see they continue to swell though and as I was making my rounds a sec ago I decided not to hit em with anymore foliar even though I do use the biological fungicide because they are just too damn fat and juicy for that I think it'd give em bud rot. I will make the adjustments and I had been wondering why it has always been right around the 3 week mark when I,ve seen these issues on this particular strain, it doesnt occour on my great white shark or power kush, this ultimate is a fast stretcer during first few weeks and grows tall and fat as hell, so that makes since with what u said at that time in there cycle is when they need more of the sea cal and sea mag cause there doin it all. thanks, I sure wish I'da caught it better this time, I noticed it right off but think I threw it all off with the epsom. So G man Im not growing in soil though its pro mix hp a soilless medium... still same suggestion on ph??? Its not rockwool hydro or coco or rocks but its soilless and nutrientless, but mabee I shuld raise my ph to that anyways??

 

[gmanwho]

i've only messed with soil , lavarock, an hydroton. soil is run higher 6.0-6.4. an lavarocks an hydro i run 5.8 solid, then late late flower 5.9-6.0

i dont even ph in veg no more, but my veg nutes usually bring it to arround 5.6

ya man, ease back on the nutes to like day 15-20, an start ramping up from there to like day 45 an then back down after 45. cut the N in half atleast. if the plants are healthy at day 52-53, i usually flush then bring them to 65ish days with straight ph'd water thats been sitting for 24hrs.

i'd go with 5.8 an see what it brings over 10 or so days.

In hydroton or soiless i am a firm believer of Silcablast at 5mil per gallon to mid flower. i also run ewc an mychorize teabags in my feed. FIRM FIRM believer in organic additives an synthetic nutes. Bsafe

 

[Mitakoye Oyasin]

thanks gman, I have another cycle of the same strain that just hit the 3 week mark and I am making those adjustments on those I did tonight actualy and we will see. I also am raising my ph on the cycle in question. Quick update, after flushing and renutrating lower than I had been the probelm has stopped progressing and new growth is comming on fast and massive and not seemingly affected. The buds are so heavy Im having to tie them all up just dropping the branches like, hopefully potency wasnt affected much cause the yeild still seems to be comming on through the roof, and the buds look really juicy!

 

[Mitakoye Oyasin]

update for anyone interested. the plants fully recovered with massive beautiful new green growth and new fat bud. No progression on any other leaves or even the ones that were affected since the last pics. if anyone is interested I will take pics before harvest which should be in the next 2 weeks or less for two of my strains in the room and still a while on the one that actualy was showing the problems. Its a 11-12 weeker, but damn its well worth it and it makes up the time lost in extra yeild. This one turns completly purle starting about 1 - 2 weeks before harvest. Only the buds not any of the leaves turn purple. The ammount of trichs on this plant is awesome, the deep purple buds look white until u get close and look close to see through the crystals. This is a realy special plant, it has just got a lot of calcium and mag uptake during the 3rd week. The other batch that I have going I learned from this runs mistakes and seem to be avoiding any definciencies whatsoever so far. Posotive energys on that one. Ill only post more pics if anyones interested and says so other than that Ill assume this post is done, thanks for your help guys. B-Kind

 

[gmanwho]

good to see things are moving along. lets see some purple action. man,telling you, these cold temps ive been hitting has been bringing some serious purps out.

b-safe

 

[Mitakoye Oyasin]

I have a strain that I am just begining in another spot I found called grow diaries. U talk about purple and cold temps. I will demonstrate this difficult to grow special strain that I call A-Love from start to finish, my temps never get below like 66f even in dark cycle and she just , well, u should just watch , sorry no finished pics of her yet but if ur patient u will see what happens in 11-12 weeks of bloom. I will be posting pics of the clones tonight.

As for the plants that are on this post, I have some pics I just took tonight and I flushed tonight also so needless to say these are some pics just before harvest. thanks for the help guys

 

[Mitakoye Oyasin]

Pics just before harvest

Pics just before harvest

These pics are taken tonight right before I flushed out for the final time with royal flush flushing agent. I have been feeding them at 25% st for the last week and will harvest as soon as the medium drys from the excessive ammounts of water poured over them tonight. B-Kind
