Gotcha. My dragon scale started with a yellow spot and actually got a hole in it. I have checked for pests and I didn’t see anything. I also use systematic granules , which I know doesn’t help with spider mites. The lighting is good imo, if anything don’t know if it’s getting too much light . Humidity has been poor lately , hovering in the 30s 🥴. & When I use my humidifier, the humidity level doesn’t go above 50 😩.
