I hear ya, chasing VPD will have you crawling the walls!! Lol.....just get it The best you can. Warmer air can hold more humidity so just get temps up and then work your humidity. The plants will respire that moisture in the pots through the leaves and into the air and humidity will rise!! But gotta dial in extraction fans or put on controller.Few questions on vpd. I see if your temps are 77 and up it suggests 70%rh? How do you keep your room that humid? I have my exhaust fan running and it sucks out all the humidity my humidifier is pumping in. My space heater also dries the room out. I believe this is why my pots are so wet. My room is 77f and 50%rh the vpd scale has that in the red zone.
