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

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
Thank you, this chart is awesome.

Did that heater help?
Yeah everything is sitting pretty right now and I'm able to keep the humidity down and the temp where I need it. Thank you so much for all your help. Ill post some new pictures tomorrow but the progress is going well
