Honestly, if this was my grow, I'd be defoliating! I've defoliated a grow right up to 2 weeks before harvest with no adverse effect... I'd want to be getting as much light into the lower bud sites as possible. But do it slowly - a little bit today, see how she is tomorrow... if she hasn't reacted, do a little bit more... etc. I trim off fan leaves that are either covering bud sites or growing towards the main stem... this will do a couple of things - along with getting more light into the lower bud sites, it will also tell the plant to concentrate its efforts on the buds themselves, not the leaves. You might want to take a look at this article which I find very helpful: https://www.growweedeasy.com/nebulas-super-simple-3-step-defoliation-tutorial
Just want to talk a little bit about the nitrogen problems you've had.... the FloraMicro is LOADED with nitrogen and it's this particular nute I cut back on first... Honestly, I'd cut that back a bit more (if not cut it out altogether) if I were you and I'd bring up the amount of FloraBloom... leave the FloraGro where it is.... but FloraMicro has an NPK of 5-0-1 which really isn't very healthy for plants in flower so I completely ignore the feed chart on this nute... in flower, you want a lot more P and K and very little N....
Good luck!
