Looks very nice, and your right IMO, that a few of the pics look ready, I do see some where the pistils have not turned or receded. It's hard to see some pics but I tend to watch how the plant is feeding and if it has stopped growth as well as pixels, I'm running hydro at the moment so it's easy to monitor uptake which helps to make decisions re finished. Again I pull just as the first trichomes are turning amber.
