Brownish and pointed, pics, please help

can somebody please tell me what is wrong with this plant. i have checked all the plant problem guides and cant figure it out. i left for a night and when i came back my plant was under-watered and wilted, it looks better now from that stand-point, but the leaves are twisted in weird directions and pointed upwards, as well as there being an odd light-brownish color covering them. the pH of my water/nute solution is 6.1 and my temp is 80F, my humidity is 40%. all of my other seedlings look perfectly fine. what is wrong? strain is blackjack and it is feminized. indoor grow under 400W MH
1st pic is b4 problem, others r the problem

anybody? please

my plant looks like its dyin people, somebody's expert advice would be extremely appreciated

okay , how close is the light? have you fed it nutes yet? how big is the pot? how old is the plant in general as well?

I am growing blackjacks right now ... lol. oh and what is the medium?

the light is around a foot away, and it is a cool tube exhausting with a 540CFM inline to my attict. it is usually around 82F at the top of the plants. i started feeding it 1/4 strength nutes of the CANNAcoco nutrient line, all of my other seedlings are receiving this and seem to love it, but have flushed and stopped feeding nutes to this one2 days ago since this problem arose. it is in a Jiffy peat moss starter plug that is about 2 in diameter. the plant was germinated and planted almost 3 weeks ago. growth has come to a halt since the problem arose 4 days ago. it will be transplanted into coco coir if it survives. the rest of my seedlings are in ready gro super propogation plugs which i believe is mostly coco. if u want more info, check out my grow log

View attachment 907882 Tomorrow is my 3 week mark on these 3 blackjacks planted from seed. They are smaller than they should be because i waited too long to transplant.

Your plants are definitely much smaller than they should be for 3 weeks, even from seed. Their lack of growth could def be attributed to you not having put them in a bigger pot yet. Or possibly the conditions that they have been grown in. What type of light are you using?
1/4th of the canna dose is what? 2.5 ml? or did you do more than that? It could be nute burn , it could def be too close to the light. I use coco as my medium and i start off with 1ml a+b through the first week, work up to 2 ml the second, 4th the third, then in week four usually mess around with higher levels.

You cant determine anything that you have done differently with this plant than the others?

the only difference is that it is in peat moss, and it got underwatered 5 days ago cux i was away for the night. that made it wilted and lighter green in color, and right as it seemed to be recovering from that this problem started. it is under a 400W MH cool tube. i use teaspoons and use it per water bottle, so per 17 fl oz. and i use 1/4 teaspoon each of A and B and 1/4 teaspoon rhizotonic.

If your using a bottle , and not a gallon jug, that could be a wee too much nutes. but your problem doesnt really look like a nute problem. If i were you , i would take that right now, put it in a larger pot, maybe even a one gallon. flush it if you havent already. and move it a bit further away from the light. Thats attacking all the problems. And you should do all that stuff anyways ( imo ). Ill be watching, please update on its status.

alright, i'll do all those things today. thx for the help. think this stress greatly increased its chance of becoming a hermie?

: / . Its early , and you never know. The seeds are fem right? but any sex can pop out of those things if they are grown in the wrong conditions. Id do what i could to save it, and if it lives just wait it out, grow it in the best conditions you possibly can, and see. : ) .

ya they are fem. im just wondering if its worth it to take another plant's spot. i have trainwreck seedlings that i planted just for the fuck of it, but they are not fem. but if the unhealthy one is doomed, i would have a healthy trainwreck take its place. what do u think?

this kid who sells around here , he always has trainwreck ... that shit is good. But the way i hear blackjack described ... i dont think id replace the ones im growin right now with trainwreck. But ultimately its your choice. I guess i would factor in the plants health though. both are dank strains. your trainwreck could possibly catch up too.

not sure if its just me, but I don't think you need to be giving that plant nutes so early, I think you have overfed your plant, and its going to die, and if it does not die, it will be stunted for growth, best to start over, and not give nutes to your plants so early in life.

ya they r fem. this is my dilemma. i planted trainwreck seeds that i got from nug from the clinic. there are 3 healthy seedlings now that came from them. I can only grow 2 plants once transferred past 1 gallon containers, and i already have another healthy blackjack fem seedling. Although the trainwreck seedlings are not feminized, im wondering your thoughts on if i should let a trainwreck take the place of the unhealthy blackjack.
