I bite the bullet and bought an entry level microscope. High school level AmScope, 2x-4x.
WHAT A DIFFERENCE! No more guess work. Snipe off a small sample of bud and leaf, put it on a slide, and you have your answer, in full color .
2x fills the frame, giving you an amazing perspective of all the trichomes on a portion of the bud. 4x actually let’s you look into the individual trichomes, and look for signs on cloud transitioning to amber.
I wish I’d done this sooner.
