all of these pics are of a diff plant. don't wanna chop prematurely so asking for the advice of experts. i don't always take pics, but when i do its' of marijuana...stay lifted my friends.
from looking at the pics you got at least 10 days to go. but there is nothing like you using a microscope to look at them, that way you will know for sure.
i wouldn't know what i'm looking for anyway honestly. 60% of the hairs being brown pretty much, right? is there anything i need to do to them in the weeks before they are ready. i heard to cut the lights completely the last 2 days...
When in doubt , wait it out .. And when you believe its done , wait a week ... Not much longer to go now , let them fill in a little more and ripen fully
