Twisted seedling leaves

I have 4 girls like these 2 of them get rid of stress and catch up with the other plants but other 2 very bad shape , cant produce leaf enough but growing in the stem. Im not sure but I feel like a ph problem with you too

this could be a bad batch of coco too... Na content is possible, if not washed enough, or improperly buffered and releasing K+ for Ca++ which would change the balance of anything you have given.. leaching cations wtih greater affinity and releasing whatever positive ion previously in that bonding site. coco is good, but if they screw up the manufacturing process it can be deadly or just take a while to balance out and then start gowing healthy plants after a rough period as it reaches a proper equilibrium with your fertilizer. every brand is capable of screwing this pooch, but some do it less often. I haven't bought enough to know fo sure which brands are best, but i'm not going back to mixing 6-12 cubic feet of peat and perlite anymore, lol. think you got all the possible causes listed here... start eliminating possiblities with information you have that is not provided in the question. if other plants are in the same coco with no problem, probably not the coco... genetics still is a possibility. some plants just have a problem metabolizing various nutrients... 1/20? 1/50? probably in that range of frequency?

The dark green in her leaves is what brings me to my answer. It is not Genetics. I had this issue before in a dwc that was too rich. Again it willgrow into it. Just give it appropriate ph water.

Hey Growmie, Yes, I have a couple of seedlings do this and it turned out it was from genetics, no I wouldn't pull it because it will eventually grow normally over time.

Yes the problem is the substrate is too hot with fertilizer. Don't add anything. She will grow into it.

I have had a plant like that when I first started. For me it was from over watering. But this can also be caused by bad environment conditions, too much food or genetics. If it's genetics then its a game of roulette. Some plants grow out of it after the first few sets of leaves while others will stay mutated but still produce a decent yield. And lastly it could stay mutated and not do anything. What you have to consider is how old the plant is and if growth is slow/stunted. Since its an auto flower time is not on your side.
