You need to feed PeakBoost to your plants as there is a higher quantity need for Phosphorus during the initial stages of fruit and flower development. Your plants may suffer from deficiencies and mineral antagonism in the medium. However, the phosphorus is buffered and protected from these mineral interactions by combining with organic l-amino acids. Therefore, you can achieve the same results or better with far less fertilizer use. PeakBoost is a better option than many other combined p/k boosters. It allows you to apply phosphorus when and where the plant needs it. The organic acids of PeakBoost can help to adjust pH down for your nutrient mixture. Your reservoirs and irrigation systems will remain free from residue as it is 100% soluble in water.
