Amnesia Haze Autoflower harvest time?

[Milkbone]

Hey all
My amnesia Haze has a flower time of 8-9 weeks.. im beginning week 11 (5 plants) and want to know if its harvest time yet?
I used a loupe and got a few pics that I attached to show you guys but I just didn't want to harvest too early or too late... any thoughts or suggestions would be greatly appreciated
Thanks!

Ok thanks man.. I just know it's a few weeks past it's estimated time and I see the plants all really starting to yellow except for one of them..
just by your eye, how much longer do you think they may need? I just don't wanna go too far past and ruin the harvest

1-2 weeks, only feed plain water
