What Nutes Aren't They Getting?

[Thundurkel]

So I have my Shades of Grape girl in my tent vegging and she was looking fine while in the mom tent under T5s and getting the Head Formula in straight Bio Bizz coco and I'm still feeding her that using Cutting Edge Solutions MICRO and BLOOM which Head worked out for me to be 6ml M 10ml B

Is she just hungry and feeding more now that she's under HID? cuz she is right in the middle...

 

[Thundurkel]

nobody? I know it takes time just want to get the ball rolling so to speak so think I should flush her of feed her?

 

[jyme]

hey bro. im gunna need some more info. whats your ph?do you know what you ppm run off is? how is the temps? whats your humidity?im not familer with the nutrents your using?whats the n-p-k on the bottles?is there micro nutes in it?do you have fans blowing on them?how close are your lights?what kinda lights?

looks like a Phosphorus defc. but i dont wanta tell you a lie.has the temps droped low in the room there in if so its posable temps below 50f can slow Phosphorus up take down and cause trouble.is the soil room temp?

 

[ChronicPow]

Specifically it looks like Mg def, use some Cal-Mag with that coco you nut!!!

 

[Thundurkel]

thanks jyme well my ph is 6.0 but I only have a drop test kit no pen.. My nutes have all the micro cuz it's a 3 part like GH but I'm using only the MICRO and BLOOM bottles like in the Head Formula which is tailored for coco so I don't see what it's deal is.. Temps haven't dropped and it stays around 80 and never gets over 85 in my tent and my room it's in stays around 65-70 usually closer to 65 though..

 

[Thundurkel]

I don't have any cal mag and that could be it cuz Head said I may need a lil Cal Mag with CES using his mix.. I have Calplex from Organicare and I have Humboldt Nutrients Sea Cal but not Mag I guess I should use the Plant Amp and Mag Amp from CES that I have?

 

[Thundurkel]

Also lil side note here my buddy who started me out stopped by and said I was burning my girls and she was burnt from nutes but he's a rock wool dude and wont switch to coco so I don't like his opinion a lot of the time..

 

[Thundurkel]

Hope it was a Cal Mag thing cuz I found out I have a way to make a Cal Mag mix with Plant Amp and Mag Amp and added them to my mix and gave her a feeding so we shall see soon being in coco. It's just weird cuz my other girls are looking great and about to take off as the fill in their new Air Pot homes...

 

[jyme]

does the bottom leafs look well? is the top leafs showing any signs of the illness?

 

[Hash Zeppelin]

Some of those leafs look mag def, and some look N def. Get a good n-p-k balanced veg fertalizer for it. Cal-mag might help too. Also if you want to add more mag for cheap disolve one tea spoon of epsom salts into one gallon of water, and then add you regular fertalizer. Epsom salts are fast active. To organially boost N. add a hand full of used coffee grounds on top of the soil. they are a 20 carbon to one nitrogen ratio. It is hard to burn your plant with it because it is slow release, but dont put more than a hand full on top.

Morning Thundur,
On that lower shot there is some leaf tip necrosis...so possibly your rockwool buddy is right. A flush may be in order if that's the case.

If you do supplement Mg, I agree with Hash Zep that Epsom salts are a better choice. No need to complicate things with the Ca unless you're sure you need that too. The 1 tsp/gal is my personal max dose and usually I use way less...like 1/4tsp unless you have a full blown deficiency.

[Hash Zeppelin]

^good point there evil twin. probably wanna start with less.

also as you were told else where it could be a light bleaching, but I dont think so. Generally when you put the plants under and HID light like hps they start growing alot faster, and a boost in nutes is required.

Maybe a few leaf close ups, because one of the leaves on the bottom even looks phosphorous def.

 

[jyme]

do my eyes deceve me or is there so really small spots on the leafs.

I don't quite understand why you are using only micro and bloom if the plants are vegging. Three part nutes generally work better if you use all three parts.

You know, you can flush coco in the morning and then feed in the afternoon, if you want. Also, a lot of coco farmers flush with fresh water instead of feeding every week or two, just to keep things kosher.

Coco is going to buffer up anything that you put in the pot. I usually start with a pH of 5.5 - 5.7, while the nutes are in the pot the coco will slowly raise the pH. The benefit of this is that you have a range of pH and you have better overall nutrient absorption because different nutrients absorb better at different pH's.

Well Pharma you must not understand that Cannabis doesn't need all that N and there is plenty of it in the bottle of Micro from what Lucas found out and made the Lucas Formula of 8ml Micro 16ml Bloom for veg and flower and a lot of people use it with great results. Head from Head Seeds found it was a lil too hot for coco and toned it down a bit to 6ml Micro 9ml Bloom and it's been used time and time again by coco growers on this forum with great results. It's like a coco a&b nute program basically without buying coco specific nutes and it's been proven to work with GH and CES 3 part series. Head took the guaranteed analysis I gave him from my CES bottles and plugged em into his calculator he uses and said that my mix would be 6ml Micro 10ml Bloom and maybe a lil cal mag if in RO water but I use tap and haven't seen a problem in my CFL cab using the mix.

Here's a quote of the nutrient mix he uses in coco..
"In the coco, I am now using 6ml/gal micro and 9ml/gal bloom which gives the nute profile:
N 97
P 60
K 105
Mg 27
S 41
Ca 97"

I hope that helps you understand better why I don't use the bottle of Grow...

Always add in a quarter or half teaspoon of mag-amped. (CES Mag-Amped is magnesium sulfate, same as epsom salts for those unfamiliar with Cutting Edge Solutions) You may need to add a little Plant-Amped (Calcium) sometimes. Maybe not.
Your plants do show a Mg def in some of those leaves. The dying tip/margin are maybe P and K?

Mag may just be deficient or your pH in the coco is too low. Starts to get restricted at 5.4 and lower. P is def. in acid medium. K can be deficient at any pH.

If the pH in the medium is low a flush should cure it, just be sure to finish the flush with new nutes.

 

[Thundurkel]

Thanks Hazy I was just asking Head what amount I would need to add to equal the amount of epsom salt he uses to the 6ml Micro 10ml Bloom mix which I've dropped to 5ml Micro 7.5ml Bloom so think that amount you said will go with the Head Formula or Rez Recipe cuz I'm using a mix of the two since I'm doing the Kool Bloom like Rez but Head figured out the mix for me and I'm trying to get my coco nutes down with CES and so far so good except this thread... I'll post a new pic cuz after I hit her with the Plant Amp and Mag Amped she pushed out a few leaves and they look good with no deficiency but I flushed her today just to be safe in case there was any build up goin on but I'll add it to the nutrient schedule I have going....

 

[PharmaCan]

I use AN three part and have pretty good results. What is the purpose of modifying the three-part regimen? I'd assume it must be for better results, because it sure doesn't seem to make things any simpler; in fact, just the opposite.

I'm not ragging on you. I really am wondering what is the advantage of what you are doing.

[hazy]

Hey PharmaCan, the use of just the micro and bloom of GH nutes is called the Lucas Formula. Lucas figured out what he believed was the perfect nute ratio for hydro.
Rez and gratefulhead modified it from 8 ml micro and 16 ml bloom to 6/9 to compensate for the nute holding ability of coco.
It works.
If you go to the stickies in the coco forum you'll find a thread explaining it better. And rez's thread is... maybe in the rez vendor forum.

And actually putting aside the reasoning and explanations, it is simpler.

Only two bottles to deal with. ok three counting a shot of Mag.

Real simple. a teaspoon of micro two teaspoons of bloom. a dash of mag. No changes from veg to bloom.

How's She Look Now?

How's She Look Now?

Thanks Hazy! Couldn't have said it better myself... Also hows this bitch look now? I've cut the feeding back to 5ml Micro 7.5ml Bloom 2.5ml Mag Amped with a 5.5-5.8 PH I think the excess P and K was locking out some of the N? Either way I think she's looking better I haven't had any leaves die since so I've plucked the burnt ones off so I can see over the next few days if I've got this taken care of....

So what do you think Hazy? I get the Mg problem handled?
