Context: We are growing tomatoes and other vegetables in a large scale
hydroponic system. We are experimenting with many different plant
nutrients to see which one grows the best plants. We have found some
successful nutrient combinations and need to know what they are
composed of.

Question: Therefore we need to locate a laboaratoty that will
"reverse-engineer" these plant nutrients, and tell us the exact
chemical and physical composition. Provide us with the name of such a
lab and why you believe they can handle such an assignment as this.
