Exactly!! Everyone has there preference as far as when to harvest, so take my opinion with a grain of salt....but, let your plants go at least a week over 2 month mark! I'm sure your clipping hand is getting an itch...DONT DO IT!! Checked out your pics again, in a more clear head....if u have a scope, that'll take care of things properly. If u don't, I'd at least suggest waiting till none of your tops have white pistils still reaching for the light. That's not a foolproof determiner but I feel confident telling U that is a fairly reliable 2nd option....along with keeping up with the amount of time you've been in flower. (Because sometimes they'll still be white and be ready to harvest!) Hell, if u get 3 weeks down the road (prolly not any earlier) and can't resist the urge to clip your plant....clip U a nice little branch off, heat it up in the oven for about 10min x2, and test it at different ripened points....you'll have immediate green to smoke on and your personal preference, for your grow log, as far as when to harvest that particular strain.
