why are the leaves twisting?

[HyppieHannah]

This is my week 3 banana kush auto in coco/soil mix. i noticed about a week ago that the leaves were twisting weird directions and looks a little smaller than my other one next to it. any advice would be helpful! thanks

Early fast growth sometimes does this I've noticed but usually corrects itself as it gets bigger. Maybe someone can post a cause if any.
