What’s this blue line in there? Are you feeding from resivour?
Co2 injection
Yeah Kelp is great stuff and ideal for stressed plants, microbes very important for organics less so with salts.
Everyone’s environment is different, fabric pots can dry out very fast in high temps and low humidity and those were small pots, and coco can go hydrophobic too.
They aren’t deficient in Calcium or Magnesium, if anything could make them worse. Superthrive is good and should help, did you do 7pH again?
Yeah higher ph on this as well
Is that run off? how are you checking your ph? PpMs,? What are they? Water with 5.8 ph water. Give some cal mag. Even in live soil. You will not kill all your microbes. Even if you do kill off your microbes you can always reinoculate. Flush it. Right now you just want to bring the ph down. You may need to do this a few times. Drying back after heavy watering is important. Dim lights just a little so she’s not stressed out anymore. Good luck. I know it sucks and it’s frustrating try to figure out what the he11 is going on! 
Read the thread 
What his ph is higher?
Like to know now, not yesterday’s
What size drainage holes do you have on your pot/ how many? How often are you watering?
@ohlordy the problem I see, my opinion, is light intensity is way too much. The thing that pushes me towards this is the purplish/redish veining of the leaf structure/connection to main leaf.
Too much light intensity can slow growth as much, if not more, than nutrient deficiency/excess problem(s).
If in veg, allow no more than 650 ppfd across highest point on plant (depending on cultivar ) without properly dialing in environmental factors.
Raise light up by 3-4 inches per day (initially I [my opinion] would raise it 10-12" from plant initially) and see (allow a 2-3 day on hydro and 3-6 day organic soil) whether it begins to accelerate in growth.
Guys as much as I would doing all your advice I’ll have to look at it in bits.
currently watering her with 6.5 ph water only with nutes and selectively as well. Growing in biobiz lite soil and feeding superthrive now, will include trace in next feed. Will only move to full nutes on her again next week if she perks up.
cannot reduce lights but I don’t think she is being overlit as my parr is not that strong.
New growth is looking better but still not great and she is farrrr behind.
Looking much better, I think the pH was definitely creeping too low in the pot. I would give her a feed or 2 more at 7pH to bring it back up quicker.
Sounds good, go easy, 
If it’s the only one in the tent acting weird, it’s usually one of three things it could just be a harmless genetic mutation (some plants just have goofy DNA) but it’s worth keeping a close eye on it. Check to make sure it’s not a viral issue like the Tobacco Mosaic Virus or some kind of internal pathogen, especially since the leaves are twisted and mottled. If you’ve already ruled out environment and pests, it’s likely just the plant’s genetics.
Y’all should do one one on plant health and virus now I have to research more.
I did wonder about TMV too but looks more like variegation so far, and they don’t cause the twisted growth like that. Pretty sure pH was low, it’s improving quickly being fed higher.
Plants are weird, when you get one out a bunch and it’s the only one acting goofy. Makes me wonder sometimes if they aren’t infected or sick. Only way to know is have it tested.
Yeah she seems to be taking off now. Will still be about 2 weeks behind in size. Will still just leave her be.
Looking better man
