Get rid of the moss and buy some Coconut Fiber substrate(not husk) and use that for her bedding. All water must be treated with a de-chlorinating agent prior to being used for your frog and that includes the water used to expand her substrate and misting bottle. Also water for her soaking dish must be changed no less that every other day
so it does not become stagnant.

Does the lamp you're using have a dimmer switch? If not I recommend purchasing one that has a dimmer switch to accurately control the amount of light and heat produced by the bulb.

Do you have a UTH(Under Tank Heater) on the side of the tank to assist with temps in the enclosure?

Correct the issues I've pointed out and see what happens.

Keep us posted.
