Any help would be great thanks

if i ever get deformed leaves ill throw in some cal mag and that help new leaves from being deformed.

if its just 1 blade of one leaf...don't worry about it bro. Don't over think it...keep it simple.

Thanks for the replys,The middle part(Im sure it has a name) looks like it has split in to 2 parts if you know what i mean.I might be wrong,Ive never has this problem before so i'm not really sure whats going on.Thanks again for the replys

Looks cool, it will be fine
