Plants require specific amount of nutrients dissolved in water to thrive. For example, it’s good to have a concentration of nitrate (NO3) 10 – 50 ppm and level of phosphate (PO4) from 0.2 to 3 ppm. When we add certain amount of dry salt (KNO3, KH2PO4, etc.) to a specific volume of a water, you will get specific concentration.
