Is your uth being controlled by a thermostat? How are you taking the temp of the uth? Is the heat bulb red or blue?
Also I agree that you should switch out the half log hide with something else. I used them before but my first snake wouldn't and then after I bought new ones he started to regulate his body temp. A good choice are reptile basics hides, they are dark, secure, and cheap. It's best to have 2 matching hides so the snake can't play favorites.
