I had two plants that went into a vegetative state and grew to 6 feet with no buds after 3 months. I was ready to trash them but they suddenly decided to produce buds and in just a couple of weeks were looking good. after a few more weeks the buds grew and the trichomes said its time but the lower branches have a lot these timy buds that never took off.Did you harvest that whole plant already? If the top of that is your "mature" buds, you may be chopping waaaayyyyy early.
As far as the popcorn stuff, save it for oil or butter, etc...
A few weeks was from end of July to now so about 6 1/2 weeksI don't know, man. Maybe you're running some sort of magic juice. But I've never had a plant go from no buds at all to being ready to harvest in "a few weeks." How about some pics of the dried colas?
