Yea, to me trichs don't look ready but the leaves do... I'll explain. Whan the palnt reaches the end of a life cycle and it's getting time to crop, it pushes all of its sugars and resins out of all the leaves into the buds as a last ditch effort to reproduce, that could be why your leaves are dying, however, high temps or not enough water could be doint the same thing. I'd wait for the trichs to turn myself. Have you started fluching this plant yet? If not and you do plan to wait a bit I might start flushing it and then pull it once you are finished flushing.
