Humidity issue and fan placement

I got a issue and not sure how to fix it.
For the life of me I can't keep the humidity up at the same time as keeping the heat down. I have a controller on the extractor fan; on medium or low I can keep humidity up but the temps get way too high, if I turn it up to high then tempa go down but then humidity drops dramatically. I've tried turning up the fans but this also messes with humidity. I have no idea what to do, any help appreciated.

Tent specs as follows -

2 fabric 5 gal pots
4ftx4ftx6ft tent
Extractor fan at top near ceiling
Oscillating fan at top in opposite corner of extractor fan
Stationary fan bottom of tent opposite corner of oscillating fan
1gal cool mist humidifier Places in front of both pots

I would add another humidifier and, instead of controlling the fan to control humidity, control the humidifiers instead. When my tent (same size as yours) has less than four 5gal pots in it, and it’s dry in the house, I have a hell of a time keeping the humidity up. In the winter I also blow the exhaust from the tent back into the room to help keep the humidity and temps up, but that might cause yours to stay too hot.

How hot is it getting? Under led you want it warmer anyway.

Looks like the same rh in both pics... but I'm sure it makes the rh rise with a wet towel... wouldn't be keen on having a wet towel in my grow tent though... not for long at least

The pic i shared was just on a day when Temps were really low outside so it wasn't hot inside and it was not an issue. Since Temps have been going up the humidity has been an issue. Right now I cant get it above 30%

That was just a good day when outside Temps were low causing inside temps y9 be easier to control
