As others have said Stress a plant out and it will try to defend itself. I read once a while ago a couple old timers chatting about an old trick to increase trich production. The trick was 48-56 he’s before harvest cut a third of the way into the stalk (one plant I had tie up after Doing this she was heavy and leaning and I cut into the wrong side oops) it could’ve been mental but I swear the Trichs were crazy by harvest not only a lot of them but the biggest I’ve ever seen. Did it on a couple and they all seemed to do the same. I’m gonna try it again when this run is ready.
