I recently grew out a Purple Wreck, and while it's great smoke, mine didn't turn purple like that at all. I think mine was more of a Trainwreck-like pheno, while yours is more Purple Urkel-like.
Yours looks male... Those are the beginnings of crab claws.
I could be wrong (and I hope for your sake that I am), but I'm 98% positive it's a boy.
Get some pollen off that bad boy!
