Hey man, looking so so good, a picture of health! I would keep feeding this week if I were you, and possibly next week. You'll start to notice some of the pistils turning orange/brown and curling into the bud - this is normal and a sign of the beginning of maturation. You can see it beginning to happen on your toppiest top buds. I'd say you still have 2 - 3 weeks to go, maybe even 4 if you want max yield, so be patient. This is the hardest part!
From our little chat last week I did a bit more reading on flushing and found an interesting study (conducted by a nute company so take with a grain of salt) that indicated no statistically relevant difference between flushing and not.

What I take away from this is the following: if removing nutes for 2 weeks before harvest doesn't affect the final product, I see no reason NOT to flush. It is just more economical, saves on some nutes and time. It also MAY have some positive effects on curing time, but this wasn't mentioned in the study, as the removal of nutes in the last two weeks encourages plant to use up energy stored in leaves, including chlorophyll, which is what we are trying to remove from the plant when we cure. Getting a two week headstart means you'll have awesome cured nugs a little bit sooner.
Based on this evidence, I am converted. I will be flushing my grows from now on and would recommend others do the same. I can't really do it with my current set up using biotabs but if I was using liquid feed I would 100%.
Really impressive grow for a first run. Quality genetics + a little knowledge is a powerful thing. Can't wait to see how the rest of your run goes. Godspeed!
P.S., I feel like a total growing nerd but I am so envious of the health of your leaves. I hope to dial my environment in a bit more for next run and have a plant looking this healthy at this stage of growth.. mine get put through their paces that's for sure!
