Well, today is day 47 and the plant is covered in about 35% red hairs, whether you can see it in the pictures from a few days ago or not. Although, the hairs don't really matter, it's all in the trich production. Also note that the hairs will turn red when hung upside down regardless of when you harvest it because they are dying. Pretty much all of the THC is in the trichs and when they turn cloudy/amber, that's when I am harvesting. There are quite a few places on my plant where the trichs are cloudy at the moment... This plant is doing mighty fine. I squeezed a nug today and it had a very dense, strong/thick, feeling. I'm very happy with the progress of this plant.
