This isn't entirely true, do some research. Peak time to harvest is actually when the trichs are clear and turning cloudy. Now before I get sh!t on for saying this, look at the HT article. Basically, the thc breaks down after harvest into it's psychoactive form. Peak thc (not CBD or CBN) is found in clear trichromes. The more opacity the trichromes have, the more the thc has began to break down to CBDs and CBNs. It's entirely up to the grower depending on what kind of effects are desired but for peak thc, clear turning cloudy is harvest time. Now, if you're like me and like the melting-into-the-couch weed, wait a while for the trichs to BEGIN turning amber (20-30%) then chop. Do this because the plant doesn't stop all processes when it's chopped. The plant continues to produce resin and such until it runs out of stored energy. When you chop a plant, notice that the leaves stay erect for some time. Then, they go very limp. They also change color after more time. So, this is between the chop and death. The buds, after harvest, will keep breaking down the thc until it ceases to live a few days later. Anyway, my point is that you should look around at professional harvest guides and see for yourself what you should do. By professional, I mean not someone that just got done with their 3rd harvest on here. Anyway, GL with the big chop!
