Week 12 royal dwarf ready to harvest?

It's at the point you should be scoping trichomes and assessing color throughout plant (on calyxes only, not on leaves). A cheap 30-60x jeweler's loup or currency checker is good enough for the task. Beward, they lie about magnification on the cheapies. Good idea to read reviews and avoid the options where people mention magnification sucks.. .i guarantee you'll find some pot growers in the comments, LOL. Trichomes -best and main guide pistil coloration nug density use all three to determine a consistent harvest point. Try early-midd-late and figure out what you enjoy best. Can always harvest bulk where you think you want it and takea bud off a bit early or leave a few buds on to ripen longer etc... staggering the harvest to cover all bases but focusing on 1 target or not. Save some time compared to 3 or 4 grows testing it out.
