If you don't see any signs of flower in the next 10 days, I would worry. But rest easy for the next week for sure.
got flowers popping up all over the place. mostly on top of my scrog, but a few under the the screen. they look amazing even young.
I'm right there also, been in 12/12 for 15 days today. Just verified my first lady and have thrown out a lot of males that have just been showing in the last couple of days. I agree you'll know something in the next week. Best of luck
