3x auto ultimate from Dutch passion

The plant with the foxtails is putting on a lot of trichomes while the other one has become a really frosty plant. The hard thing with the foxtails is that it’s hard to tell if a plant is mature enough to be harvested, because the trichomes of the newborn calyxes(foxtails) can’t be checked because are too young and the core of the bud, where the actually mature trichomes are, is unreachable with the microscope. I’m going to chop her when the foxtails are maturing and almost all pistils become orange.
