Dunno why the ? about "autos". It's just a hybrid that's been tweaked to go into flower on its own timetable. It's cannabis.
53 is a bit dry. In veg, 60% is "ideal".
Truth be told, the real thing to look at is temperature + relative humidity which are rolled into one number called vapor pressure defect or "VPD". VPD is akin to the "feels like" temperature for humans.
Oh yeh, you're from Ohio. If you're in south OH, you've run into humidity*. Not as bad as, say, Florida but roll back to what it's like at 80° and 80%. That sucks. That's because at 80° + 80%, sweat doesn't evaporate, it rolls off you and you feel sticky. But drop the humidity to, say, 40% and it feels a lot better because perspiration can evaporate.
Plants are impacted in a similar way - when it's 80+80 (warm and humid) plants can't give off moisture like they can when it's 80° and, say, 50%. That's tough on a plant because if they don't sweat ("transpire") they can't cool off but they also can't take up nutes.
Just like humans, 75° and maybe 60% is pretty comfortable. 80° is hotter but it will feel pretty OK if RH is, say, 55%. So it's the
combination of the two numbers that matters. VPD is the "feels like" number but for plants.
53 is a little dry. Most times you'll want to be at 60% in veg but, as long as your temperature is say, 70's to low 80's, your plants will be in the "feels good" zone. That's called having VPD "in range".
You
might want to jump into VPD but there's no
need to do so. People grow great weed without knowing about VPD. OTOH, if keep VPD in range, by adjusting temp and/or RH you will, over the long haul, get better results from your grows. You'll tend to have less hassle during the grow and your crops will tend to come out better but it is one more thing to deal with.
And autos are the same as photos in this respect - like they are in the vast majority of areas.
This graphic might be helpful in setting up your grow environment. I used it as a check list because it helped make sense of it all but it also helped me get to the point where I don't have to do much with my plants. It takes a few grows to get things nailed down but, after that, you should to not have to d*ck with things very much and just let the plants do what they know how to do.

*I was stationed at Ft. Knox and I learned about the Ohio Valley humidity first hand. It could
really suck.
