I was thinking that myself! i had a look at the trichs under a microscope my gf got when she was a kid, the lowest magnification is 96 times!! real detailed view of individual trichs, they are beautiful, prob is that it may be too close as its dificult to get a good idea of their clarity cloudiness or amberness, they kinda psychadelicaly have an amber aura around them, do think this is a sign? a message from the god of weed?
hard to tell with those pics but looks like it could go a little longer, hairs don't look as if they receded much yet.
Nice looking plant, if you don't have a Microscope, then go by the red hairs, the whole plants is red u r good to go sir ! HappyHarvest
