Nutrients

The elements needed by plants for normal growth and health. The major nutrients (macronutrients) are nitrogen (N), phosphorus (P), and potassium (K), but there are numerous micronutrients which also have integral roles in maintaining plant health. A good quality hydroponic nutrient formula will contain all of the major nutrients and micronutrients needed by the vast majority of plants.
