Is it ready ?

Looking great, buddy!! You have a quite large harvest window. So just harvest a tiny bud which will dry soon, and smoke it, for thc content check. Also you want to make sure, that there are no white pistils developing anymore. The last 2 weeks can give you up to 25% more bud weight!! From the moment where the buds don't change anymore, you have 1-2 weeks time to harvest, so no worries, it's a very personal decision when exactly we harvest. You can always also harvest only a part of the plant. I would wait a week more, just from remote and the few pics it's hard to say, just my gut feeling! Have a great chop and a wonderful smoke, buddy!!

Forget the "few days without light", it is BS. Extended darkness just stops a plants metabolism and a plant with a stopped metabolism CAN NOT magically make any extra trichomes or THC. Just harvest in the morning after a normal night. Flush/withold nutrients for 7-10 days and then harvest.

You don't want to judge the trichs on the leaves... look at the trichs on the bud itself. But she's probably close - can't tell from your pics if she's started her fade in earnest... just can't tell, sorry! Good luck
