Has any one else grown nypd from nirvana and got purple pheno?

I started 4 nypd's about a week ago and three outa four are already sarting to get purple leaves. Ive heard of this happening to a few other people. I think its kinda weird that they are only on their second set of leaves and are already turning purple.

havnt, but sounds like good news for you! =D hope it comes out as potent as advertised and you'll have one helluva good lookin/feelin smoke
