Does anyone know what’s best for extracting the humid air out of tent in terms of getting it to come down also. I have a 6” exhaust and a 4” inline on a 4x4 tent with 2 vents open to comes down to like 55% but after a water day goes back up to like 65-70 will be in flower soon so want this down. Is it better to seal the vents up and have it so the tent walls suck in or is the vents open and running the fans highest speeds all can do? Got a dehumidifier but only does 350ml a day so gonna get a 45 litre one instead

What's the humidity in your lung room? A better dehumidifier should help significantly.
When you go into flower you will need to keep the tent sealed up to prevent light leaks. You will also want negative air pressure in the tent (the walls sucked in) so any odors go through your carbon filter.
Sounds like you need to keep your inline fan on high and get the new dehumidifier you mentioned.
Are you watering to run-off? If so, maybe water less but more often.
