I'm also growing New Purple Power in the Northeast and mine haven't started yet (I can't even tell if they're F or M, though I'd imagine if they were males they'd have shown sex already)- I'm actually psyched to hear it's not just me because I was wondering the same thing. I have one other plant that's unknown and one plant that's some kind of squat Indica that started flowering about three or so weeks ago. I've already taken out 5 males that became apparent over the past three weeks, but none of those were NPP. I was under the impression that this wasn't too late a flowering strain, but it's definitely taking longer than some of the other ones in the garden.
