I have a Sour-D auto that is pushing 14 weeks and still no or very few cloudy trichomes and no amber trichomes. I am growing it in a 20 gal DWC bubble bucket and she is generally healthy looking.
I have read an article on Leafly that the amber is caused by the THC-A oxidizing into CBN. Some studies suggest a synergistic effect of CBN + THC in treating insomnia, which is what I’m growing for. So I want the amber trichomes.
If all of the above is correct, is there any way to promote that oxidization? I have considered backing off my lights and shortening to 12-12 (they have been on 18-6 throughout the grow). Try to reduce temp (which remains stubbornly around 74/23C) in my grow tent? Any other thoughts?
