Any advice for my set up 7 weeks into flower.

Its 10sqft tent with 2x viparspectra xs2000 running on 75% power only.

Should I set the light strength to 100% power? It's at 7 weeks flower now. Fan speed at 7, should I add another fan or boost the speed up to 10?, 10 seems a bit too powerful

And also do I need that fan blowing onto the leds? The drivers get pretty hot so I was a bit worried about it.

I'm surprised that your drivers are getting hot at 75%, a fan across the drivers might help.

that equals 36w/sq ft, which is fine.

More fans? Sure, hard to have too much air-circulation, under the canopy too.

Also kinda looks like a bit too much N & maybe the start of K deficiency.
Check the ph of the run off, might be too low for K uptake

Good luck
