Keep a fan around them while drying, not pointing at them though. Trim fan leaves and hang plants whole. Start checking sugar leaves after like 5 days or so for them to start getting crispy. Once the stems and leaves are mostly dry is when I trim, then I will put in jars. I check/ open the jars at least 2x a day if not more, if they feel too gooey I will dump it all into paper bags for a couple hours and back into jars.
Once you start doing it, its not as scary I promise lol. I was scared to death I was going to fuck up all my smoke the first couple grows, its really not as deep as it seems sometimes. IMO your temps and humidity are fine, I know plenty will disagree but I don't think I've ever had temps lower than like 75 and rh is never where it "should be" while drying. Only had mold in a few SUPER dense colas once. I'd rather have it too low than too high, can always smoke over dried weed, cant smoke moldy buds though
