mites or trichomes?

Edge of leaf curling a bit looks like heat or light stress

Yes those are resin glands nice!!

Those are trichomes, no doubt about it! I would worry a bit about the holes as something has been nibbling here and there. You might want to get either some BT or some Dr. Zymes and spray both top of and bottem of leaves to take care of any pests that might be lurking you can't see. They're both organic and can be used right up to harvest. Do make sure they're getting bloom nutes now and that you're easing off on the grow nutes... Good luck with the grow! Nice friend you've got!!

There is trichromes on the developing flowers. Hole in leaf could be a hungry critter or gnats. It's developing pretty good from what I see, and growing. Easy nitrogen and a good diet of potassium and phosphorus. Look for any hitchhikers to identify and treat. Keep going your doing good from what I see. Happy growing 🌱
