Okay, well, after looking at your diary, you are about 2 weeks into flowering too soon.
She only really came into pre flower on week 7. And after checking the guidelines for that strain, she is a quick 1 at 30-35 days. So you are about 4 weeks in so id say by guessing in around 10days she should be in the harvest window. She's very close. Check the trichomes, and cut when you are about 95% cloudy 20-30 % Amber pistils and hang dry her whole as cool as you can. Give her water an hour or 2 before harvest to prolong the drying time. A longer dry as cool as you can will make for a nicer smoke.
Now for flushing you'll get a mixed bag on here. But I think most of that is down to what way you see flushing. Soft/hard flush. So the week of harvest if you want to soft flush and let your plant finish up eating what's left in the substrate you just wanna cut feed and feed as normal with just water for that week.
Or you can cut feeds but do a hard flush (lots of run off) until you bring down the EC and let her finish off quickly. The soft flush is better method.
So, anther week or so and check your trichomes to see if you are in harvest window.
Good luck pal.
