Hi Bub1972
She looks great man.
No need to worry.
This is what Autoflower marijuana is going so popular.
No Nees to change Light schedule for Autoflower Marijuana.
No worries off slight light penetration during night hours.
I have been doing my Autos on 16/8 always.
They don't need change in light schedule to Start flowering.
Normally about week 3/5 you will see pistils appear and bud sites start forming. Whatever you do.
No way slowing her down she will Flower when she's ready.
I have a few in my Diaries you can have a look.
Good luck with your grow and hope this helps.
