As I test my grow room temps this is the range it runs with light and exhaust on this time of year. Humidity is generally around the 50 to 70% mark.
Is this temp range okay for Autoflowers?

70%RH is a bit high for my liking...you're getting to 70% with an exhaust fan running?
Given...I'm right on the edge of a semiarid high-mountain desert...but I operate
in the 20's-30's %RH most of the time.

70 is at the very extreme. I'm by the coast so it stays at least 50% most of the time.

You wouldn't want to risk 70% in flower bro, could cause you trouble.

mold and bud rot...right, D&SC?
May want a dehumidifier on hand just in case.
I would imagine mate yeah, I'm like you, never get above 30-35% and have never had any issues, but 70% humidity in any enclosed space is risking it I would say. Saying that, I'm of the thinking that high humidity is actually better than low, it's easier to take water out of the air than add it IMHO. I've often considered a mini humidifier in the tent but I never got round to it and don't see any adverse effects of low % up to yet.
I think 75-83 is fine temp wise.

70% is unacceptable bad. That is definitely a recipe for mold. 50% would be a lot better for your girls, especially in mid to late flower.
I see you said that's the RH and temp it runs at with lights and extraction on, do you turn the extraction off? If so, don't! Extraction always stays on, turning it off and having 70% RH means you will get mold.
I live in a maritime environment and it gets humid here in the winter. I had to put a dehumidifier in the room my grow tent is in, but it really saved my ass. Highly advise.
