Is it ready?

It's possible but you likely have a couple weeks yet. The trichomes are the only way to know for sure, but judging by the stigma, you still have 3-4 weeks. Some stains will push out fresh white stigma until they are ready to harvest but in general, you want nearly all of them to turn orange first. I would wager that your about 6 weeks into flower at this point.

Always trust the trichromes, and when your growing in soil you will need to flush for at least 2 weeks before harvest. So start easing off the nutrients and wait to harvest until your seeing mostly milky trichromes and some ambers

No, probably a couple of weeks yet. Wait until 95-99% of the pistils have turned brown. I would be easing up on the nutrients though, she is very, very green. Hope this helps,......... Organoman.
