Temp is good if you're using led but a little high in my opinion if you have HID. that humidity is fine.

That is a VPD of 1.7 (depending on your leaf temperature of course)
I don't think there is any chart that will give that as a good VPD.
1.7 means that you have a greater chance that the stomata will close to prevent evaporation.
Closed stomata lead to less CO2 absorption (thus less photosynthesis) and therefore less growth.

How are the flowers coming? I have a 600w HPS and day temps average from 77-81F and humidity from 35-45 depending on how much water is in the pot. Here is mine at day 20 I believe

Try to lower your temps a degree or 2. Sometimes that makes a world of difference. Otherwise should be good! Next time, don’t butcher your plant lol if the plant doesn’t need a leaf it’ll discard it!

Honestly, I’m not sure. Maybe lower the temp of your house a couple extra degrees. I have my lights on from 6:17 pm-6:17 am. This morning when I checked the plant out, temps were at 77 because it’s naturally cooler in my apartment.

There’s the problem, so during the day when I leave for work at 7, I set my thermostat to 77. My night temps don’t get very cool. She likes it though. And my day temps at 6:17 are about 81. When I get home at 6:30 I turn my thermostat back down to 72 and when I go to bed at 10 I set it to 70. Bring your temps down in your apartment and it’ll lower your tent temps. Sacrifice a bit extra on your bill lol

I have high ceilings too, my apartment gets cool. You might need to change your air filter. I just got my vacuum cleaner and sucked it clean lol
