Curly/twisted leaves

Less ferts and water. If thats an auto kill it and grow a normal strain until you learn.

Hi mate, I would check your root zone for condition and keep a closer eye on your PH. In. my experience when leaves have grown that way my PH is off which then causes lockout and root problems. I hope this helps, good luck and happy growing

Toxcity would be my first shout looks like they are locked out have they been growing slow aswell if so its probably the case jsut try your best to get the nutrition in the soil down by flushing the soil. though your gunna haveto be careful not to over water her at the same time. Im sure they will recover though if you just wanna leave them I have seen much worse looking seedlings lol best of luck :)
