Flowering Problem

I am growing 3 sativas, been in 12/12 for almost 9 full weeks now...and still no signs of sex. I know sativas are supposed to take longer but this just seems ridiculous. The room is completely dark during lights off, and there are a few light leaks but it's still impossible to see anything. I put them in 10/14 now to try and kick out flowering, maybe this will work. The last pic is of one of the bottom branches off my healthiest plant. Any advice?

they look over or under watered, something there isnt right.

9 weeks under 12/12 and you should be nearing your end my friend, you have a bad light leak and have wasting all this time - however... they should still by now have shown signs of sex i would imagine.

simply put - your not getting 12 hours of darkness.

10/14 is NOT a good idea. Breaking the 24hour Natural schedule is bad enough, but to take away the minimum 12 hours light could stunt your plants growth for quite some time.

keep it 12/12 and total darkness you say theres light leaks then thats what the problem is. nutes for bud n6/ph10/po20 water 200ml every 48 hours total dark no light leaks

It is completely dark. And yes I know they look thirsty, I just watered them, I was a little late in watering them this time. I guess I'll just wait and see cuz they have been stretching like they do in flowering. And I said they're sativas, so 9 weeks isn't even close to done, as they're advertised for 11 weeks but I've seen other people's grows and they harvested them at 14-15 weeks.

turning lights to 10/14 does make you flower faster but ur buds will be smaller and less dense is the only thing.
