Hi, after the plants have begun to flower for about a week, i already culled the males but there are three plants that have no flowering at all. anyone have this before? they look just like the females, small, a bit bushier, but no balls and no hairs... they've been on 12/12 for 3 weeks. any help would be appricieated. Thanks.

Hmm...that's strange. All I can say is be patient, in that case. I'm not sure what else you could do, other than make sure your timer is right.

how much light you using

I have about 12,000 lumens of cfl 2700k lights. The timer is definately set on 12/12. I was wondering though, could I set it to 11 on and 13 off?

Shit, well, I'd say wait a bit longer. Any sign at all of preflowering? What cycle did you have them on for veg?

Are you sure that there is no light leak that might be affecting those three plants? That's the usual cause of that issue.

They all three finally showed me their vaginas today! Whew. No no light leeks. Different strain maybe? it came from some good bag weed that usually don't have seeds. It could have gotten mixed with two diferent male types or something I have no idea.
I veg with 5500k Cfls at a 16/8 cycle.

Any pictures? Can you visibly see pistils?

Yes I see pistils finally today. I have mo magnifying glass so I have to rely on eye sight only. But I ended up with 5 females out of 8. So I'm pretty happy about that. Sorry, no pics atm but I may put some up in a day or two.

Good to know they finally showed for you. It is interesting I will keep this in mind...

Hell yeah, Man. That's a pretty good ratio, too. Good turnout. Keep us posted.
