Dude, I'm growing a sativa plant right now. I cut all the flowers off but the bottom 2ft down. The first cut I did at 10 weeks flower stage. I began flushing two weeks ago and most of the leaves are discolored. I still have over half the leaves on the lower part green. I just gave is 5-1-1 fish fertilizer with 1/2 tsp P-K mineral rock, and of course
cal-mag supplement. All of my first flowers are milky white with a few ambers. Now, the existing flowers are still mostly with little amber and its four days from the initial harvest. My plant seems to be in slow motion lol. Not drinking as much water.
My goal is to get ALL ambers, hoping that everything (THC, CBD) turns to CBN. I want to be able to smoke hits of the last harvest and sleep walk to my bed. lmao rofl. I don't know the outcome of letting these buds grow until the plant dies; but, its exciting to find out.
