Sounds like you are doing a lot of things right. Congrats. What are you feeding her and what type of enclosure is this? Reptile prime is a great substrate. Are you feeding live or f/t ? Common for bp to go off food occasionally. Some will stop feeding if there is a impending shed cycle, if they are ill or otherwise uncomfortable and others go off food once they reach 1,000 grams in weight. I would start with tweaking the enclosure. Start increasing the feeding interval to 14 days in any case.
