I think you’re right on track for a pretty good yield. I’ve only done a few grows, but half have issues with fan leaves eventually. once I know they will die I cut them. By about day 60 I’ve only had a few left and finish with just sugar leaves. I figure sugar leaves still do photosynthesis so as long as they aren’t dying I’m good. Still somehow scrape by to a pretty good smokeable product. So, you’re on The home stretch here.
