Hey there madnes, nice trich shots, they're getting their mushroom heads and youre at roughly 6 weeks of flower? So with the pistils changing colors and curling inwards id say they're only going to need maybe 2-3 weeks more. I feel like an 8-10 flowering seems to be the common time frame. Just keep checking them every 2-3 days and watch for the high amount of milkies and that'll be your harvest window open. Clear trichromes racey high, milky ideal high, excessive amber couch lock, grey plan to fall asleep the window has closed.
Great job with the grow, happy holidays and harvesting. โ๏ธ๐๐
