I take it you're looking at the brown tips on some of the pistils? At first I thought it was because of the close proximity of my cfl's, but they are doing the same on quite a few buds that aren't so close to the light. I know I have some tip burn from letting the leaves touch the cfl's, but it's minimal. I thought the browning or reddening of the pistils was just a sign that they are getting mature? I have 2 trainwrecks, 1 white widow, and 1 bubble gum kush. I was told to expect 6-8 weeks flower on the trainwreck and maybe 7-9 for the other two.? I was thinking that the pistils were just doing their natural thing. When do you prefer to harvest? Do you look @ trichs or the overall appearance of the plant. I was thinking that I would wait until I started getting a lot of yellowing, dying lower leaves.?:stoned:
