I feed my crickets both flukers "diet" which is their main source of food and contains a high concentration of calcium and vit/min (so they are more nutritious for your frog) and flukers "quencher" which is easier than trying to keep water in the cricket keeper, and is an additonal source of calcium. As I said, my frog has done well with this for almost three years, but the above suggestions of a varied diet (for frog and crickets), and dusting along with gut loading sounds like good advice.
