Gold1answered grow question 7 months ago It's quite common to have to give some phenotypes a few extra weeks in the tent. If your plant isn't producing any new white pistils, its probably close to being finished. The only true way to determine when the plant is finished is to get a microscope and check the trichome color. When majority of your trichome heads are milky/amber is when you're going to want to harvest.
Your plants look good friend, very frosty. Good job and good luck with the rest of your grows :D
