Look at the hairs and if about 30% of them have turned from white/clear to yellow/orange you are ready to harvest.30% !? Are you kidding me? Thats WAYY to early. I have a plant with 30% colored hairs right now and its not even close to being ready. If you go by the hairs I would say 80% at least. I go by the trichomes and the swelling of the calyaxes not the hairs.
