Strange Twisted Growth and Leaf Discoloration on Single Plant

[ndawg420]

So I've run into this issue on a single plant and have spent considerable time troubleshooting it and have an idea or two, but really want some opinions.
The plant is New Berry #6 from clone - ever since getting the clone it seemed to have a bit of irregular growth that's only gotten more pronounced. Im attaching a few pics here, hopefully this is allowed, but so that I dont have to repost everything, I have a very thorough documentation of this grow on growdiaries - https://growdiaries.com/diaries/56765-pineapple-express-cosmic-serpent-8-new-berry-6-grow-journal-by-lordevolde

It was suggested on there that it could be N toxicity, so I did a flush a little over a week ago before going into flower and although at first I thought I might see some improvements, it hasn't changed much.

Current feedings are RO water with CaliMagic (about 1.5ml/gal) to bring ppm to 150 (500) then 4.5ml/gal Canna A/B 4ml/gal Boost, and just started adding 1ml/gal PK13/14, as Ive seen many state to run the pk at low dose, then hit hard at weeks 3/4 rather than Canna's recommendation of only week 3/4. pH is 6.3-6.5 - Keep in mind Im using Coco Loco, and following FF's ph recommendation of 6.3-6.8. Im certainly willing to deviate though if someone has evidence that their recommendation isnt accurate.

Some of the leaf discolorations looked like potential pests, but Ive found no evidence, and the canopy is quite intertwined, so Id expect them to make their way onto other plants by this point. My current theories are A) Maybe Im UNDERFEEDING it too much? B) Light stress (I know some strains are pickier than others) C) Shitty genetics.

So far nothing I have done has dramatically changed this issue. The other clone to its left is doing great, and the plant from seed on its right is doing even better, although I can tell all of my plants need a stronger feeding and will be getting it shortly, theyre not quite as "lime" as the pic, the mix of 3000k/4000k cobs was doing weird things to the coloring on my phone when I moved it around it seems. Im open to any suggestions For reference, in the pic of all three plants, its the one in the center if you haven't deduced that by now lol.

Its most likely the berry genetics that's causing the twist leaf mutation. I've run into it running blueberry strains myself and its nothing to worry about, just the genetics. You see it with cookie genetics, ogkb phenos also. You look like you have slight yellowing, what your ec, ppms?

I was wondering that myself I found a post where a guy went on a rant about blue berry genetics but havrnt managed to dig it up again lol. Feeding around 450ppm/.9ec now was only around 400ppm, but starting to think I'm pretty far on the low side. Planning to bring that up when I water tonight.

Ya you're on the low side, I sometimes do that also, worrying to much about overfeeding. I found my sweet spot is around 800 ppms, peak about 1000-1100ppms, never try to push em past that since I grow alot different strains. I use r/o water also and sometimes use half tap-half r/o, swear my plants like it more when itshalf r/o -half tap.

So wait are you in week 1 or 2 of flower? I use canna also but im in soil so I use vega and flores as my base. I really like canna. Thought you shouldn't be using boost or pk if youre that early in flower though. The pk is some strong shit. I don't use the pk and I grow fire bud.

Week 2 now, and yeah only using 1ml/gal right now of the pk they normally recommend feeding 8ml/gal week 3-4, but if you think it could be causing me issues I can try backing off for now. As for the boost their schedule recommends it all flower until flush but I've started it off light.

Some strains are very sensitive to that pk. The quantity canna suggests would honestly kill some plants. I fed half strength to a GG#4 and it's burnt it to hell, my friend had same issues

 

[ndawg420]

Interesting, in tonight's watering, I dropped the extra pk, at least take a variable out of the eq until its needed, I dont see a specific deficiency that calls for it? Upped the A/B feeding to 6ml/gal to get me around 600ppm, prob still a tad low, but just want to see how they react first before taking it further.

If it were me, I'd take a closer look at my pH...good luck.

They said they're keeping ph at 6.3 to 6.5 which should be good.

Honestly i think you're loving your plants to death. That flush you did probably stressed them out a bit. I'd say drop the pk, think you started using it to early. Like I said the pk is no joke,you only use tiny amounts.
One thing I can tell by your pics is something is off. You should have some nice flower sets by 2 weeks into flower, at least I do. 2 weeks in I have pistils popping everywhere, and even trich formation getting going. In your pics I can barely see flower formation. Maybe just cut back and just use the canna base nute with cal mag. Maybe use half r/o half tap. Maybe the pk caused some problems but your ppms seem low to cause any lockout. Think your girls could be hungry.

If this.....ph of "6.3-6.5"......and the OP also said they are going up to 6.8 according to the manufacture's suggestions..... this is too high for a coco grow, in my experience, which in turn is going to cause the OP issues. If they were in soil, the pH noted would be ok. Anyhow, just my two cents. Good luck.

5.8 -6.3 in coco. 6.8 is way to high, didn't see that. This person is obviously going by reading labels to much. Coco loco im assuming is a premix coco that could be running hot.

 

[ndawg420]

I started fox farms recommends 6.3-6.8 I personally have stayed in the 6.3-6.5 range. You're correct that it's an amended coco blend that starts out quite hot - I ran calmag only for the first couple weeks. For clarification it's on flower day 10. As for ph i agree that I've always read coco should be in the 5.8-6.2 range but was simply going by what fox farms and the limited posts I could find on loco stated. I'm certainly willing to try lowering it, just stating that's how I ended up where I'm at.

Yeah dropped the pk and increased base nutes, the cosmic serpent on the left already improved coloring, this one not much of a change so far hah well see on the next light cycle. As for flowering it just hit day 10 so I wasnt too concerned with development yet but maybe I should be?
