Plants look nice @Plantbmore .
The 70% Rh you have in the first pic is good in veg but too much for flower. I like to stay under 60%, ideally closer to 50-55%to keep them drinking fluids and using nutes. A good dehumidifier is a necessity to keep bud rot away from your inside plants. They throw a good amount of heat though,so be ready for that.

Just be careful when you get one. The little cheap dehumidifiers for closets don't work well-they're called thermo-electric dehumidifiers and they don't utilize compressor technology. I would be sure to get one big enough to dehumidify your "lung" room and not just the closet. Any 20-30 pint dehumidifier should be good. I've been using a small Homelabs dehumidifier every day for the past year, keeps it right at 50%, no problems with it whatsoever. Good luck!

Plants look nice and green @Plantbmore. You didn’t give much info about your medium, water ph and ppm, lights….. so it’s hard to say if they need more feeding, but generally I increase my ppms/EC up to week 6 and then back it down a little every tank.
