The hairs truning red/brown are just part of the ripening process. The buds will swell and gain significant size the last 2-3 weeks of flowering. For harvest, I trim all large leaves then cut plant and hang for a week to ten days. Next I place buds in a paerbag for two to three days to handle any extra moisture. Last, I put buds in mason jars and open jars for roughly three hours a day to let extra moisture escape and prevent mold. After about a month of curing in mason jars, the buds are ready for consumption. There are several really good threads on the site about various methods of harvesting and curing. I am by no means an authority but the method I use has worked well for me. Good luck!
