I imagine that's nute burn on the leaf edges, but whatever. In case you're following along i obviously don't know what i'm doing. My "pruning" game is garbage. All the same, i'll start a 2 week flush now and harvest in 2 weeks. Trichydoos are mostly cloudy so i think it's going to be okay. Plan to take all the good stuff off the top and let the lower buds that aren't getting enough light have some more time. Not sure if that's good or bad, but i figure top stuff is good for smoking and the bottom less developed buds can be used for cooking.
