Stop soaking her. This could cause stress that will lead to not eating. As long as the tank humidity is good (or provide a hide filled with damp sphagnum moss), she will hydrate on her own. She needs to focus on eating. I would feed her every 4 days, if she'll take it, until she is solidly over 150g. You can reduce frequency then if you want to. Also, why are you making her wait until tomorrow for heat?
