2.5x1.8 meter coco scrog, 3 strain bingo!!

um thats pretty much what i told you....thats why i do a heavy..light...plain schedule is to make sure i dont get a salt buildup and eventual lockout.

i would just do a plain ro water and not worry about the light nute feed until they dry out again...

Well its not highly recommended to flush coco with plain water leaving them no feed, and I`d only do it as a one off if I`d fucked up in the first place, which I`m thinking I may have done. I don`t as you suggested ever feed with anywhere near full strength nutes, if you do I`m not surprised you have to keep flushing mate. ;-)

Rather than feeding heavy, light, plain, you` be much better advised to get the feed strength adjusted to the plant`s liking in the first place. I`m not saying an occasional flush is harmful in coco, I dont believe it is, but I dont think its a good idea to have it as a regular routine, and I`d definitely prefer to leave them a little food afterwards. Thanks for your advice `n all, but my problem isn`t going in with full strength nutes.

I`m suspecting that it may be, as Scroger suggested,that the Calmax strength was too much and caused a problem with the delicate balance of Cal and Mg in the medium causing the plants some difficulty absorbing the Mg through the roots. I upped the strength of Calmax from ec0.3 to 0.4 when I saw the problems starting with the Big Bud, trying to compensate in order to give more Mg. I think maybe ec0.3 Calmax was a bit strong in the first place and starting to lock Mg out. I`m thinking the Big Bud pheno was most susceptible and showed signs first. When I upped the Calmax I think I may have provoked the problem further and the BB got worse and the Armageddon then Grapefruit started to struggle too. Since Scroger mentioned the Calmax stength, I reduced the Calmax to ec0.2 and started feeding enough for a good flushing run off on a daily basis and gave the plants a good foliar feed of Epsom salts.

I`m not sure about this, but they certainly look a little better in both colour and vigour just 30hrs after their foliar feed. but the Big Bud still look poor but they were by far the worst affected so that wouldn`t be surprising. I`ll keep a close eye on them and keep you all up to date.

I hope this is the problem as its gonna be so easily remedied if that`s the case, its far more likely a scenario than some plastics off gassing, thinking about it I think that would show different symptoms to the Mg def look, it sure did in the grow tent.

I`m wondering now if it might be worth mixing my RO water with tap water to bring my base water to ec0.2, it`d save money on Calmax for one thing, and would overcome the problem of too much Nitrogen especially during heavy flowering. It feels like sense to me to give this a go to maybe just one tray of plants and see how they like it.

I`ll take some pics tmro and post em up. I`ve been looking in on the tent grows, they`re looking impressive. The buds on the flowering plants are growing and swelling well and I think they`re somewhere like 5 weeks into flower now. The 4 plants in veg are looking good too. I took some pics of both tent grows and will post them tmro too, as I cant find the cable that hooks up the camera to the computer! Its some good bud porn though fo sho!

As I said, I`m not certain this is my problem, but I`m feeling a bit better about the prospects of this grow now, and to my albeit limited knowledge of the unique way that coco uses and stores elements, it does fit I think. Let me know what ya think guys??

Cheers for now, Toke

i understand where you guys are coming from...but ive been feeding my plants this way for 4+ years and the only time i ever had a problem was because i was doing heavier feeds without a plain or light feed. its been suggested by (lucas?) when in coco or peat to a.)either do a 1/3 every feeding or b.)do a heavy feed once or twice a week and light feeds the rest.

I`m suspecting that it may be, as Scroger suggested,that the Calmax strength was too much and caused a problem with the delicate balance of Cal and Mg in the medium causing the plants some difficulty absorbing the Mg through the roots. I upped the strength of Calmax from ec0.3 to 0.4 when I saw the problems starting with the Big Bud, trying to compensate in order to give more Mg.

Yeah Man I really think this is the issue, reading the symptoms closley on the leaves. If you can address this issue at least you can tick it off the list once you've run some control trials, as you sort of are doing now!

Dude, you may be getting fine results using this Heavy med light regime/method, but its NOT the correct way to do it. You HAVE TO chart your PH to see what the plants require next in terms of EC/PPM's, theres no other proper way of reading a plant, and now you know man! Peace & G'Luck

btw, I gave up listening to Lucas a long time ago man! He's advised you in a laymens sort of way, so as not to confuse people i suspect, its justa safe way to give nutes but its not the correct way.

LoL dude no reason to flip...just telling you. i consistently get 1g/w with the way i feed. i also am a scroger. i DONT chart my pH EVER and get great results every time. but i guess im just lucky right? i know what my plants need by looking at them. reading the pH will give you hardly any indication at exactly what is going on. if you cant read a plant than why the fuck bother doing this.

Whooooo Whos fl;ippin, i aint flippin man, cool down bro! So you get good results here great man, just the sdvisde you are giving aint quite the correct way to do things thats all, its great your results are fantastic & im happy for you bro. If you wanna do things properly though listen to what im saying man, i wasnt being an arse, i was just trying to show you the correct way to do things!

Seriously

No your not lucky at all, you have been taught a noobs way of doing things by Lucas thats all, please dont take offence. feeding nutes the way you are is a very safe way to do things ok man.
YES you can read the plants PH drift to tell you exactly whether the plant requires more ppm's or less ppms. Dont be embaressed that you obviously did NOT know this growing Knowledge, its nothing to be embarresed about at all. PH gives every indication of what the plant requires interms of EC/PPM's, believe it or not. Im a big believer in reading plants & inm glad you do this, as not many do, you can read a hella lot from the overall looks/stature, the leaves, colour etc, but you can only trully read the PH drift to see what is required next in terms of feed! FACT!

Hey ya misunderstand Sgroger, he`s on your side dude.

Your way no doubt gets results mate fair doo`s. I reckon you could do better that`s all. I can gaurantee your plants could be a little happier still. I`m not suggesting that`s important or necessary to you, but that doesn`t leave your way of doing things coming out on top. If you read pretty much every bit of advice given, other than lucas, it would tell you the same as Scrog and I are tel;ling you. Lucas isn`t reknowned for his coco growing advice to be fair.

But hey dude, we`re all mates here and all have a similar aim, stick around, post yer grow too

To be honest mate if you`d read just a little of my thread you`d have known my feed strengths were considerably lower than full strength, but hey no probs there bro, we all do that from time to time. Pull up a comfy chair, and roll yerself a fat one:friends:

Hey Scroger, fingers crossed, we`re onto it here, thanks for provoking my brain in the right direction.

Cheers, Toke

Here's to hitting the jackpot on this one Toke buddy! Sorry man, but i have to set things straight, if things are a little wonky ie- the advise LOL! No offence Ismokekush, like Toke says were all buddy's here man. I aint no Troll thats for sure & me & Toke have known each other for a while by now here on IC, & its been an absolute pleasure if i do say so.
G'Luck on this one Toke, I think yes run some controls & pinpoint this or these aspects down & your onto a winner imo! Oh Yeah Baby!
Peace & Max Respect.............Scrogs!!

The grow looks good tokesome. That Mag deficiciency is haunting you again! You say it only affects the Armageddon? Get rid of that strain?

Or??

Hey dude, missed ya popping in my room there. No mate, I got rid of the Cheese that I`ve had problems with and of the 3 new strains the Big Bud is worse affected, Arma`s next (not too bad) and Grapefruit least affected. But rather than ditch any strains here, I want to resolve the issue, all the strains come from good known producing phenos and hope once the issue is resolved that I`ll be sitting pretty for a while to come.

Cheers, Toke

Yeah man, a pleasure for sure.

I`m hopeful we`re onto it here. I was hoping a few big guns would show up too bro and set me straight, but maybe its got everyone foxed a bit.

ok well glad we're all on the same side..i dont even follow the lucas formula to tell you the truth, but i do like some of his ideals, and i dont even grow in coco anymore...now peat and soon to be switching to shredded rubber... !...but all that aside...id like to see this work out for you. it could possibly be some sort of salt build up...but honestly the plants don't look bad at all. sometimes worrying to much and trying to fix a problem can actually make a problem even worse. it seems like my plants can sometimes just grow out of any problems they have...right now i have a batch of clones that i got from a shady character(er!) and they ended up being the weakest most yellow clones i've gotten. but they grew out of the yellowness and are now bouncing back healthy..

have you had this problem without the screen? maybe an airflow problem? the screen itself? i've never used metal fencing for my screen before(i use trellis net). are you using co2?

by the way...i do have a grow posted here at the moment..https://www.icmag.com/ic/showthread.php?t=170516 come stop by if ya want.

Yeah I`m well aware that you can end up doing more harm than good, but believe me mate, I`ve had serious issues here. The other thread in my signature shows this very clearly.

Happened prior to scrogin too, the screen is plastic garden trellis, 2 inch squares.

Hopefully I have this issue sorted now, but I`m not gonna hold my breath yet.

Good to see you`ve got a thread up here, wow and some size grow, and legal too!! You lucky man!

Cheers, Toke

hi ts and scroggs ive been on here a few days catching up with whats going on and who's growing what ... ive had alot of work being done to the house so ive been decorating (the misses) you know what i mean lol and ive had a few scrare's with these idiot workers. Am seeing light at the end of the tunnel so to speak ..am going to set up my big flowering room
and am modding my veg wardrobe with new electrics.

Sorry to hear about your problem ts a good selection of plants you have too it looks like the problem i had a few grows back- a right royal pain in the arse.
Hope you find the answers to this prob soon as i know the pain it causes heres a pic of the leafs off my white rhino

Hey R high, glad you`re getting over the builder scare. I`ve had workmen around lately, and they`ve got to come back again yet, its a hassle, but I can cope with it whilst in the veg stage, locked grow room door, 1 light left on and fans switched off and moving a few things around.

Hey it looks similar mate, did your leaves get worse or is that as bad as it got, and did affect yield and potency?

My Big Bud are considerably worse, the Arma`s have a few leaves that are worse than that, and the Grapefruit about the same as yours. Yours looks like a similar but less significant problem.

I`ve just been doing some tucking under the screen and I can say with confidence that things have improved, better colour and faster growth rate, I thought they`d slowed down a bit.

They look like they`re loving it again. I`m going to try a mixture of tap and RO water with the next res mix and see how that goes. I feel it will probably work ok.

I`ll get back and post some pics a little later.

Next lights off I`ll foliar feed the Big Bud again, and consider whether the Arma`s and Grapefruit could do with another dowsing. The Big Bud have improved a bit for sure, but they still look in need.

Cheers Toke

hi ts
Am sorry to say my white rhino's got worse after that pic was taken i added mag from canna's single range but i think i made it worse -locking a range of nutes out
but the taste and yield didn't get affected to much ... .. my last batch was chronic and it had iron def from week 2 of 12/12 and these things looked worse than your current problem
the taste was affected and the yield too..... so iron def is a right bitch to have and i would'nt wish it on my worst enemy ..... dont worry too much good luck ts

Well RH, I hope your new set up runs deficiency free.

Here`s a photo of the Armageddon in the grow tent. Not too even in the canopy, something I want to address in this larger scrog I`m running. Still they`re looking very promising.



Here are my 3 rows of plants. I reckon the screen is around 60-70% full now so I wont leave it too long before throwing the switch to 12/12.

nearest is a poorly Big Bud, the other 4 Arma`s



Armageddon



Grapefruit, fisrst 4 plants with a Big Bud at the far end



The Grapefruit



I can see a clear improvement, the leaves that were lightly affected have regained some of their green colour, the badly affected leaves, particularly on the Big buds show some improvement, but are still quite bad.

I`ll hopefully spray with Epsom salts again at lights off, if I`m up in time that is!

Cheers, Toke

they do look better ts so the epsoms must be working for them ... if i get mag def again i'll try your method it seems to be working for for you .
good to see a improvment

Yeah, it definitely seems to be having an effect, I think its important to address the reason for the deficiency/lockout in the first place. I`m hopeful that reducing the Calmax to ec0.2 has done this. . . . . . . . . We`ll see eh?

One thing, after spraying and drying out there is like a blotchy film residue left on the leafs. Is it a good idea to follow up a couple of days later with a folliar feed of fresh water, or is it cool to leave as is??

Toke

Hey toke mate, glad that it seems your on top of these issue bro... I was gonna suggest... just to know it's not something you maybe doing feed regime wise... stick a plant in compost in there... In a compost that wont need feeding for at least 3-4 weeks.... this way you can rule out if its an issue with your feeding regime, a lock out or whatever... If you just add plain tap water to the compost and get the same symptoms then you can rule out everything bar an environmental issue - temps RH gas off.

I would also use a mix of tap water and RO to get the 0.2 u require... this way calmax is also out the way as a suspect.

Everything looks good in the latest pics, lush n green
