I run the room around 50% rh and around 72 lights out and between 76 and 79 degrees lights on during flower after about week three or four depending on development of buds

I don't change my temps there's no sense in dropping the temps later in flower. The only thing I'll drop is the humidity and it comes down late in flower. Other then that it stays in the 55% range.

I've read some people say some terps can start to evaporate after 78F+.
Is this not the case?

I've only heard about people decreasing the temp towards the end to force out purples. The evaporation is after the plant is cut. I keep my plants in the low 80s all the way through, and the terpenes stay nice and loud.

I'm in a damp area, so to keep temps around 82f, my RH is between 60-65% during lights on, and around 66f and the same RH lights off.
Is that okay?
I can't really lower room RH anymore than that.

If lowering RH isn't an option, make sure you have good air circulation in the tent. The deeper into flower you get, the more humid it will be. Bud rot at the end of flower is heart breaking. Maybe look into buying some damprid buckets for your lung room?

I'm in week 9 of flower right now.
I just got moved into a 4x4 flower and 2x2 veg tents, so this is the first time I'm learning the environment in tents.
The lung room is 20"x30", so I don't think buckets would do much for the RH. I would have to look @ a whole house dehumidifier setup.
I dehumidify my entire basement with a 50pint dehumidifier from Amazon, I think it was like 250 bucks definitely recommend looking into something like that, it'll also help heat your room up a little at night probably

But a 50p dehumidifier is going to run the same $ as an extra 600w light running 24/7.
Good product has costs associated with it. You wouldn't drive your car without a radiator would you?
600w running 24/7 is like 30 bucks a month, and mines probably only on about 50% of the time. 20-30 bucks a month is worth not having to dump your entire harvest in a trash can

What's your exhaust like? I live in a very humid region during the summer, and use two 6" inline fans to duct out the excessive moisture. My plants only caught bud rot once, and that was during my first grow.

Put the bucket by your intake. Its better than nothing, I've seen it in action.

6" 390cfm exhaust/passive intake. If I run the exhaust too much, I can't maintain temperature @ 82F.
With it @ 100% I get around 60RH but 70-72f leaf temps.

I'm running 3- 220w lm281b+ boards a friend let me borrow until I find a light I like if that helps at all.
The drivers are attached to the boards and don't come off.

You live in a cold humid place? That's odd. Maybe put a space heat near the intake?
