Roseman is right (duh!) To me they look like they have some filing out to do but I don't know that strain. What does the seed provider say? 8 weeks? I start checking when some of the hairs turn colors and watch them like a hawk from then on. Then it's just a matter of what type of high you are looking for. Mostly clear - not ready, Half clear/half cloudy - head high but not strong, all cloudy - head high - strong, 30-40% cloudy, a few clear and the rest some form of amber - Cut it - it's done and at max power! Everyone does that part a little different. My LSD/BC grow is in about the same stage as yours. Are the buds sticky yet? I'm going for one more week of full nutes and then water only and a little rough up to help them finish strong and sweet. On the first grow I was told to wait until you think they are done and then wait one more week but that was before I have a microscope. That's almost fool proof! Let us know what you see!
