i think i figured it out if someone can verify this assumption of mine to be right. I noticed that when ready to harvest those trichomes [or sticky bubbles you look at to see if they are clear/cloudy/amber in a microscope] move from the surface of the leaf to the end of the trichome where you see the bubbles...like using this trichome picture again, they start at the bottom of the trichome and end up at the tip of each trichome then turn the cloudy and amber colors.....if anyone understand what im sayin if im sayin it right?

I noticed my one plant is startin to develop those bubbles at the bottom of the trichome on the leaf surface, but i wait to harvest when that bubble get to the end and started to get cloudy/amber...*AGAIN THIS PICTURE IS FROM THE TRICHOME CHART*
