Humidity and General advice

Yup, if the ir gun is correct. That's why higher temps while using LED is bueno. Mine is usually -2 or -3 difference. How far are your lights away? And what light? Watts?
 
If this is your first grow I wouldn't worry too much about sticking 100% to that chart. It's more of a guideline to keep you on track. Not being in the "zone" isn't going to kill your crop

running 2x 240 watt qbs at 21inches from top. I just checked again and its around -6 for the very tops of the plants
 
1.2 and up from here on out imo . The heater should def help lower rh and raise vpd . Then you'll notice your plants drinking more. Then late in flower they slowwwww down of water frequency
 
Usually 5-8 degree swing. If the range is too far (cold) you may see some purpling.. some do that intentionally, others wait until the last 2 -3 weeks to drop temps. Glad I could help, I'm sure you'll get more opinions. :joint:

Most defol before flip and at 21 day mark. I wouldn't worry about herms w/ defol. That's more environmental imo.
with your temps on the low side, that rh is acting higher than its reading. Look into VPD. Vapor pressure deficit , here's one I use.

- if you raise temps to 79-81 (if using led, 81 is good) the RH will drop on its own. If you lower temps more the rh will rise faster and easier. I'd look into controlling the temp/rh for the room , then you'll see a difference inside the tent. But yeah defoling now will help, and help your buds
