Grab a pocket microscope (at least 60x magnification) take a close look at the trichomes, so the heads of them are still transparent, you have to wait a little longer are they milky can harvest if you don't want to hit your body like that. If you want to have such a stoned effect on your body wait until about 20 up to 40 percent are amber and the rest is milky. In my experience, most people harvest 20 percent amber when they are milky. But you should always wait at least until the trichomes are milky. Oh yes, and when you look at the flowers with a microscope, don't look at the sugar leaves
