pictures only tell us so much...we can't really bust through it and stick our eyeball on your plant bro...but yeah she looks done...as much as that means
the last one i harvested off my first grow was a reject plant i mistook for having bud rot when near the end of flowering the smell went weird. i kept her in the living room for a couple weeks. all in all probably left her bout 2 weeks longer than what i would of. fuck me i was ruined from that stuff.
an extra day late wont ruin ur smoke but bein too early is just depressing
I just hold my bud under the lights and take a good deep look into the trichomes. If you see a lot of "diamondish glittering" the trichomes are still clear giving the shining effect. As the bud matures you see this glittering be less and less untill some day it's just not shining but more of a white look. (some sativas will keep making clear trichomes so you might have to harvest before the shining is ALL gone. I have a microscope but don't use it for determining ripeness anymore.
All this being said i think your bud looks like it's ready, but you want to harvest ripe trichomes.
