Diff for Humidity

Hi. I'm suffering with major humidity problems here. I'm in 7th week of flower Nearly 70Rh at 20c lights off and 45Rh lights on at 25c. Am I OK closing the temperature diff to zero at this late in flowering? I've tried everything else. A/C,Humidifier in grow space and in lung room. It's just to humid this time of year where I live. And my AC unit is not great or not operating properly.

I deal with the same thing every grow just about.. I keep plenty of fans going. Also I make sure to rotate the plants every day or two to get not only light at all of the sides, but to breathe as well. Knock on wood.. no mold scares.

This was with lights on 2 hours after a feed.
Lights off was ridiculous. Up near 80%. Too cold out so the AC won’t kick on, and too humid out to open a window.
I just make sure I have my fans clean & moving air really well. I won’t even consider wind stress/damage as it’s minimal compared to mold spores imo.
