Thats a bit much for an adult.
Fill up the feeder once a day with more than enough crickets. Put them back in the bin after an hour or so when she is done feeding. Calcium can be every other or every 3rd feeding, d3 calcium is once every other week, same with vits, every other week. Also check your d3 levels of the powder, some brands can have 1000 times as much as another. Sticky tongue farms indoor d3 is so low its the only calcium you need, for example.
Adults will eat alot less that growers. Just at the end of mines last growth spurt, it was 2 dozen crickets a feeding, 3 months later it was 3-4 adult dubia a week.
