What size is your tortoise? What size enclosure is he in?
- You live in AZ. Your tortoise should have a safe outdoor enclosure for fair weather and you should put him outside for at least an hour a couple of times a week. If he's large enough, he can live outside full time with a heated night box for shelter and a burrow for summer.
- No purple night bulbs. Use a CHE on a thermostat. Like this: http://www.lllreptile.com/products/36-zoo-med-150-watt-ceramic-heater on a thermostat like this: http://www.lllreptile.com/products/13883-zilla-1000-watt-temperature-controller
- Compact florescent bulbs are not effective UV sources and some of them burn reptile eyes. I wouldn't use them. Use a long tube type bulb. Aracadia makes the best ones: http://www.lightyourreptiles.com
- You don't need indoor UV if your tortoise gets outside once in a while. Here are some enclosure ideas: https://tortoiseforum.org/threads/outdoor-enclosures.121732/

- Please take a moment to read the threads that Joe's Mum linked for you. All of this and much more is explained in there. Your tortoise especially needs improvement in the diet. You are feeding the wrong foods. This, in combination with the lack of UV, can cause the problems you are seeing and eventually kill your tortoise.
