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
