Time to harvest?

Light deprivation doesn't do anything, just a heads up. Here's a link: https://youtu.be/R9yj_sVm2QA

If you want to be sure, good idea is to buy magnifying glass, or cheap hand microscope. Then look at trichomes, by their colour you can judge exactly if she is ready and what kind of high it will give. Clear trichomes - not ready Milky trichomes - more energetic Amber trichomes - more sedative high

Yes. She's done. I'd start your soft/hard flushing process if you even flush She's done. Lower your light to 70% for ripening. Then when you finished. Dark rest that whole for 36-48hrs. And then hang dry whole max at 18c (try not go above this) And for RH between 55-60....60 been optimal. Good luck
