Could just be wrinkled leaves, but without knowing the medium it's hard to say if it's too hot for seedlings or not.It's just in some soil I got from the shop some time ago. No nuts in the soil temps don't go no lower than 25 or higher than 27. The lights are on 24 hours still will be going 18/6 in the next few days
ones on far right look little under fed (peace)imo it's just genetics, have seen it here & there. Just popped some F2's I'm working and all the one's from a specific mother had the twisted leaves. Otherwise they're growing well, healthy, no worries imo. You can see a couple of them in this pic below but there's about 6-7 from that batch with this trait. Same father, 2 different mothers that created the seeds. Don't mind the runt, I had put it under the platform to cull when the cup dried out (no light to speak of) as it wasn't going anywhere. When I went to clean up a few days later it had taken off, lucky 13 from a batch of 16

Cheers, it's actually a light directly behind it that's causing the colours to show up much lighter than they are, any pics of clones or seedlings in front of that light always look almost translucent. I use those blurple LED's in this cabinet but the pics suck in that light so I turn it off for pics.ones on far right look little under fed (peace)
