yep, still too early. You might switch to 12/12 and/or give some blooming nutes to help it along a bit. I've just gone through some sexing, unfortunately had to kill one big one so far. Two or three others are lacking white hairs right now, including 2 of my four biggest. On the bright side, I've got three healthy white widow chicks showing lots of white hairs! (Sorry, no pics)
Definately don't kill it until you see the balls though. You've got a time period before they can do any pollinating. From what I've discovered recently they'll all pretty much look like your picture until they're ready to either show you hairs or balls.
