Iron is a nutrient that all plants need to function. Many of the vital functions of the plant, like enzyme and chlorophyll production, nitrogen-fixing, and development and metabolism are all dependent on iron. Without iron, the plant simply cannot function as well as it should. Symptoms of Iron Deficiency in Plants

Altering the pH is critical because a slight deviation can lock out essential nutrients, hindering plant growth. We also measure electrical conductivity (EC) to assess the nutrient concentration in our solutions. A precise EC level indicates that our tomatoes are getting the right amount of nutrients without risking toxicity or deficiency.
