COCO COIR VPD vs. OCD...

I am trying to better my environment for the girls on my 3rd indoor cycle. I have been successful in spite of my errors but my buds are airy and kind of bland like they are drying on the plant before their maturity. I think the issue stems from extreme temperature and RH shifts. My room is in an unfinished basement. The basement runs in the mid 60s in the summer and mid 50s in the winter. ( during the extreme cold snap this winter, the room dropped in the 40's). My night temps in the flower room would drop to the mid 50's. Still I was hitting 90+ if I didn't open the door at lights on. I have upgraded my exhaust fan and am now keeping lights on temps at 73-77. I have also added a small IR heater that keeps things in the low 60s during lights off.

So even with these changes my RH is too low lights on. 30% ish and too high lights out. 70+... Do I need to be in an optimal VPD range 24/7? Should I supplement the RH with misting or extra watering? (Full disclosure.... I may be underwatering to overcompensate for my first sins of overstating....) Or should I chill the hell out, burn one and wait to see if the temperture fixes will help things all by itself... Over thinking as always. Thanks!

I believe that maintaining VPD is most important during the lights-on time.
