Wow...that's a HELL of a mutant you have there...I say grow it just to see what the hell it becomes...Since it doesn't even look like cannabis, or appear to be growing as such.
Sorry I disappeared on you man, I'm still following, I was, unfortunately, in jail from Thursday til Saturday and my grow was taken by the fuzz. Long story, and for legal reasons, can't go into much detail.
But as far as the twisted leaf, it's nothing, it'll grow out of it. And the small yellow lines, I guess i'd have to know if your giving it any kind of nutes and what soil it's in, but it doesn't look serious. I however, have never really had to deal with to many problems. With the exception of the fact that my grow was taken from me, i've always just been kinda LUCKY. But we'll see if that's all changed...
