Why are there no tomatoes?

OK... I have a beautiful garden going. 8 tomato plants.... bunch of peppers, eggplant, green beans, cucumbers, squash. All doing great... except my tomato plants. They are like 5 feet high, beautiful and green. Even flowering, but no tomatoes.... not a one. Why is that? I live in NW Florida. I water every day at 0500 for 15 minutes. I use miracle grow. I have really good soil and compost. An d everything else is doing fine. If you need more info to answer my question please ask. Thanks
