I have a pastel female that's been off feed since late October. She hasn't lost weight at 1300+ grams. What I did was- moved water bowl: nothing, take out a hide: nothing, feed different time of day: nothing, feed with lights on and off: nothing, I now just moved her from a 64qt tub enclosure that she was in to a 27qt.

They will go off feed. That's the nature of the beast. So longer than others and at different times in the year and age/size. No need to panic if they're healthy. Just change attributes about the setup give it a few weeks and try to feed again.
