trichomes are an environmental response from the plant, so if you decrease humidity the trichomes grow more to catch more humidity, if you make it colder the trichomes grow more (you're at 26, should be 24/25 max during the day and 20 at night) , i see you're already putting PK, so also try to combine with a chelation agent like bacteria, enzymes, or humic acid, it really help. for the terpenes you can add also molasses to make it sweet... so that's for the grow, when you cut and dry it is the big difference also, so work on that slow slow dry if you want medical quality. Hope this helps ! 🚀
