I have 3 plants at 10 weeks flower. I want a good head high and no couch lock but not sure weather to harvest now or not. The buds are all sticky and aren't getting any bigger. My problem is the trichs - at the top of the plants they are all milky and some have gone amber but the bottom ones have crystal clear trichs. Any advice would be most welcome. I don't want to crop too early and waste the last few months but on the other hand I don't want to be glued to my couch.
