Brumation?

[ImNotYogi]

My girlfriend and I are still new to this so we worry easily. It's getting quite chilly here and our leo has barely eaten since Saturday. Ate about 10 or so mealies Saturday and I don't recall him eating any last night. I put a good number of worms in the bowl thinking they'd wriggle more and be more enticing. I didn't count how many that were in but it looked untouched. He shows no interest tonight (though it's still early.) We couldn't find anything on when leos start to brumate (age wise) and he's just a little over 3 1/2 months old.
He's been eating regularly since day one. Even ate a few worms within the first hour of getting here. The temps are good other than ambient but I have a heat lamp on now.
Edit: We turned off the lamp (blue 75W Exto Terra heat bulb) and turned on the space heater.

What are the temps in his tank?

Cool side is 75.3F and the hot hide is 94.5F I turned the thermostat (Hydrofarm) down a little since the space heater is on. He ate a mealie earlier but looked like he was sleeping when I removed the hide to get a better read on the temp gun.

Edit: He's starting to perk up a little more now. Ate a few mealworms and was give a small waxie. I think he has a thing against that worm bowl. I toss one or two in front of his hide some mornings and he eats them up but will walk over them in the bowl. The lack of appetite might have been brought on by the combination of drop in temps in the area, light bulb, and drop in ambient? His UTH is always on and is only adjusted when need be.
