We need you to be more specific in your answers.
It's great that you are feeding crickets and salads, but how many crickets? How much salad is being eaten?
When you say 78%, do you mean 78 degrees? If so that is WAY too low. The absolute minimum temperature required for proper digestion to occur is 96 degrees. And younger dragons even like it hotter than that, around 105 at the basking SURFACE, 90ish on the hot side, and 75-80 on the cool side. And this of course has to be measured with a proper instrument, one that can actually measure exact spots, not those dial thermometers.
Also, no lights should be used at night. Any light is going to disturb your dragons sleep. You don't even need to provide heat at night unless temps in your house are dropping below 65, in which case you would want to use a CHE.
You only mentioned two bulbs, a heat bulb and a red bulb. Do you have a
UVB bulb at all?
