Are you referring to the wrinkled leafs? I would probably say it's a ph issue so check that first also are you feeding them anything yet because they shouldn't need any nutrient yet If in soil.
It could be the genetics. A few years back I was reading a breeder's article on a kick-ass strain he had that had crinkled leaves- a blueberry strain, if I remember rightly. He said it looked weird but the smoke was superior! Hope that is the case with yours! Granny
try to get the ph to 6-6.5 that may be the cause but I doubt it. I have a strain like the previous poster mentioned that just had weird wrinkly leaves. Either way she looks pretty damn healthy I wouldn't worry too much.
