Answer: Your petunias may be lacking light. They need at least 6 hours of sun, even in our low desert, and morning sun is better than the hot afternoon. When you water, be sure to water slowly and deeply to moisten the entire root area. Don't "sprinkle" lightly, which allows salts to accumulate in the root zone, which can kill the plant. I recommend following the product instructions. Fertilizing every 7-14 days should be adequate, even in our conditions. Overfertilizing is just as harmful as underfertilizing! Good luck!
