Looking good.You’re a good bit away from chopping her down. She will start to tell you when she’s getting close for harvest. Her larger leaves will start to yellow as she drains the plant from nutrients. You’re kind of right about the hairs but what you’re looking for is when they start to curl back towards the buds. When about sixty percent have curled back she should be about ready. The one and only true way is to check the trichomes. Get yourself a jewels loupe 40x or greater and learn how to check them for ripeness. It’s pretty easy and not rocket science. So when magnified the frost on the buds resemble little mushrooms, it is the tops of those little mushrooms that contain the good stuff THC. Basically there are three different appearances to the trichomes clear,cloudy and amber. So clear ,not ready, cloudy and full, the head’s will swell up and get heavy and might even make the trichomes bend over, almost there. The reason we’re still waiting for the ambers is we want to chop her too soon. There’s probably still some clears that will turn cloudy and some cloudy’s that haven’t finished swelling with THC. So waiting on 10-30 percent ambers insures she has reached her full potential Sorry I rambled on but Stoned I am.
