Vegetable Garden Not Producing?

We planted a garden Mother's Day weekend so mid May, and we planted according to tag spacing guidelines etc. Some plants died, (most of the strawberry, raspberry, and blackberry plants). We lost 2 cucumbers due to bunnies, and the others are doing great getting big, etc. (squash, tomato, corn, peppers, and eggplant.) My question is the tomatoes are small and the others haven't produced yet.

Is something wrong? I weed and water and even put Miracle Gro soil and plant food. The plum tomatoes are brown at the bottom; the only ones doing great are the cherry tomatoes and the Big Boy ones are the size of a Clementine. So what am I doing wrong? Any tips would be helpful.
