why to which comment? the microscope? the plant matures different on various parts of it. as for the microscope i have no clue. i find that viewing the trichs hanging off the end of the leaves tells the truth. you can get a full side angle view that tells you if the trichs are fully mature. (Golf ball shape on a golf tee). if this is fully present than it is a mature trich. as for if it is amber.. only a few wont hurt just know you are nearing harvest and enjoy!!!!!!!
