Welcome to the forum and the wonderful world of snake keeping!!
A few things I noticed...
A) that cool side needs to come up. 75 should be an absolute low, but you should be aiming closer to 80.
B) those stick-on analog thermometer/hygrometers are unfortunately junk. They're wildly inaccurate (up to 15% or 15°). I suggest grabbing a few digitals.
C) VERY IMPORTANT - are your heat sources regulated by a thermostat????
D) Unfortunately, you shouldn't be handling the snake at all until it is eating consistently. I highly advise new keepers hold off on handling entirely until the snake has eaten 3 consecutive meals without refusal. You'll have 25+ years to handle the snake, but it's important to get the animal eating asap.
E) Many people suggest using identical hides on both sides of an enclosure. This way the snake won't choose security over thermoregulation if it prefers one hide over the other.
F) lastly, you may need to feed live a few times before transitioning to F/T, depending on whether the animal was eating live or F/T for the breeder.
Good luck, ask any questions you may have, we're happy to help.
