give em time, sometimes they will go awhile without eating, mine went for over aweek and then started eating again, dont worry yourself as long as there tail is big..
Try just putting a Calcium dish in her tank at all times so that she can lick it as needed, and dust with a Multi-vitamin and a Calcium once a week, then just feed her regular undusted crickets and mealies the rest of the time
I just supply a constant dish of calcium in the cage, they can get it when they need it.. One of my geckos wont eat dusted either. But I've seen him licking calcium out of the dish, so he knows what to do.
