When is the best time to harvest?

[frebo]

Last year I cut about half of my Shishkaberry/Doc's Medicine cross when most of the trichs were cloudy and a few amber. Three weeks later after cooler nights and purple buds I harvested the rest of the plant. I entered a cannibus contest that came with testing. The first harvest had thc at 21.38, cbd's below 1 and cbn's 2.44. The second harvest the thc was 17.8, cbd's below 1 and cbn's 1.0. So, is this typical? Anyone have similar results? Anyone have shishkaberry ?

I have never grown shishkaberry but I can say that THC will start to degrade if you let your plants go to long! Thats why there is a "harvest window!" You want to harvest sometime within this window! Maybe if you had harvested the second time around about 1 week later you would have had better results! I harvest window is not very long! Maybe others can chime in!
