I have had her since August,I feed her a mix of Lettuce and Tortoise food once a day. I have both a basking and UVB bulb. I soak her once or twice a week.
What brand is your "tortoise food"? Broadleaf weeds, and an assortment of leaves and flowers are the best diet for them. Many online tortoise places sell a "Testudo" seed mix. I got one that I really like from tortoisesupply.com.
