Ok so I changed some things up... I uped the under tank heaters to 90F. I put a big water bowl on the hot side and a medium water bowl on the cool side. The rooms ambient temp is 83F. I took the tinfoil off of the tanks to allow for the air circulation to regulate better. I placed my sensors in a better spot and I put a damp old tshirt folded in about a 4in by 10 inch section to cover the middle third of their screen lids. Also I messed with the substrate a bit. I mixed aspen with some off the coco husk and sphagum moss and of course all tanks have two humid hides a hot side one and a cool side one... Humidity at last reading was avg of 60 in the tanks and 58 ambient room humidity. I finally think I've done it and just in time as their all looking to be starting shed cycles. Thank you all for the helpful input
