The present invention is incorporated in a three-part primary nutrient system for facilitating the growth of a plant in any growing media. The first part of the nutrient system comprises calcium and nitrogen and is devoid of phosphorus, potassium, magnesium, sulfur, and trace minerals. The second part of the nutrient system comprises nitrogen, phosphorus, potassium, magnesium, sulfur, and trace minerals and is devoid of calcium. The third part of the nutrient system comprises potassium, phosphorus, magnesium, sulfur, and trace minerals and is devoid of nitrogen and calcium.
