You should be good to go to clean up the under growth like you were main lining up to 20-25 or so days in flower. Maybe that could help your concerns on humidity.
But I think you probably okay at those temps and humidity. They are obviously loving what you are giving them and doing to them. So times it could be just better to wait till the next run to make those slight improvements we all look to make.
I think are thinking right. Four in 7-10 gal containers, vegged and trained right are the best way to go in a 4x4 tent.

Yes I have a fan underneath and I defoliate every couple days. I'm sure they do like the humidity but I'm worried about bud rot. Everything I've read says to try and keep humidity between 40-50% once the buds start getting bigger to avoid it. Last time I grew which was about 5 years ago I didn't pay much attention to humidity at all and lost probably a quarter of my harvest so I'm paranoid about it this time.
And I'm growing in 100% coco, those are actually 2 gallon containers, in fact two of them are only one gallon. Coco requires a lot less medium but I have to water/feed every day...which isn't helping the humidity either. I don't like soil because last time I used it (FF Ocean Forest) I got a horrible fungus gnat infestation and got tired of fighting them...switched to coco and never saw one again. Plus even though it's a lot of work I enjoy mixing nutrients/additives every day and having complete control of what they're eating. Coco is like having the benefits of hydro and soil at the same time.
