Phosphorus is a structural component in DNA and RNA and is needed for root growth and flowering. It is a major component of chlorophyll, and it is necessary for many of the plant’s enzymatic reactions. Nitrogen is assimilated into amino acids, the building blocks of protein. Its main responsibility in the plant is regulating vegetative growth. Nitrogen is considered the most key nutrient needed for plant growth. Plant essential macronutrients include nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Macronutrientsįound in larger amounts within the plants, macronutrients are often involved in major plant processes such as photosynthesis or are key structural components at the cellular level. Regardless of their concentration within the plant, they are all equally important. Plant essential nutrients are classified as either macronutrients or micronutrients, based upon the relative concentration within plant tissue. Hence why you need to mix a perfect hydroponic fertilizer providing all of these nutrients.

If any of the nutrients are deficient plant growth will be affected in some capacity. These nutrients are considered plant essential and have specific roles within the plant. All plants need certain nutrients for growth.
