This plant looks healthy so I'm not too worried, I just wanted to verify this isn't abnormal...? I'm growing 3 other strains, none of which are curling leaves like this.

i think it looks fine

Well they do say noobs tend to over analyze, and I normally wouldn't worry about something like this since the plant appears fully healthy. Its just that none of my other plants are doing this (although they're different strains) and plus this plant is just plain ugly with all those wavy leaves lol. Maybe its just the strain, idk... If I had 2 BM plants I'd know but oh well.

bud pageants now thats new

Lol, no they're not! Thus the satisfaction of mj p0rn... But my concern is not that it's ugly, I just said that because it is . Some leaves are wavy, some are curled and claw-like and I don't see any other plants looking like this. The pics don't really do justice to the plant's appearance, so you got to look hard
