Humidity and temp issues with 4" fans

I'm hydro so lots of water. I have AC infinity 4" fans. Should be good for a 4x2x7. Thats the veg tent and the closet is a little bigger.

Flower has two 2000w leds 2 circulating fans, 3 fans under the canapy blowing up. 4" hole for air.

Veg is two 1500 leds 2 circulating fans 2 crap clip on fans

Everything is on full blast 24/7
Lights on 81deg 65% rH kPa 1.1-1.4
lights off 69/70deg 65-70% kPa .6-.8

outside temp never over 74 deg or 55% rh

Fans are going to full blast with the lights off to get the humidity down. Not helping. What can I do? I have small dehumidifers but hard to fit and going to fill up so fast. Do I bump up to 6"fans?

Thanks in advance
