Here is your main issue " you think", BP husbandry is not a I guess or I think it's a "I measure and I know my temperatures" on both cool and warm side, and "I provide proper husbandry".but it was 73ish degrees I think.
If you do not know but guess you cannot provide proper husbandry, and if you do not you will sooner or later deal with anything from food refusal, stress, aggressive behavior and health issues.
So the first steps are to know what your husbandry should be like (See caresheet) and the second is to provide said husbandry using the right tool that are at your disposition.
