Why wont my outdoor container garden thrive? - outdoor containers

I have a container garden outside where we live, because our yard is all rocks. There is no land to plant in, but I wanted some herbs and vegetables.

I have tomatoes, peas, garlic and herbs. The tomatoes seem to remain so. There is more, nothing. Died suddenly and Peas (Vining on the side of the house, I think that indoor cooking There are all in California) and is just bigger.
L of water per day, with Miracle grow soil.
Is there a secret that I do not know?
