I have a question as well regarding the same thing so i figured someone could maybe help me in this thread instead of needlessly making another..anyways i'm a first timer with no grow experience, had a good outcome but with no access to a microscope to see the trichomes i dont know exactly when to harvest but it looks like it's getting close, the hairs on the bud went from white to all of them being dark orange and i've been monitoring the crystals building up on the leaves by the bud because i heard when they stop producing crystal on leaves hairs get dark and bottom branches/leaves start dying/falling off
