PHOSPHORUS BOOSTER Peakboost is organo-mineral phosphorus booster that improves blooming processes and stimulates the production or proteins, plant hormones and vitamins. Phosphorus is needed in higher quantities during the initial stages of fruit and flower development. Phosphorus tends to get locked up in the growing medium and become unavailable to plants. This results in deficiencies and mineral antagonism in the medium. By combining with organic l-amino acids, the phosphorus is buffered and protected from these mineral interactions. This ultimately means you can use far less fertilizer input and achieve the same or better results. Peakboost is a better option than many combined p/k boosters because it allows the targeted application of phosphorus when and where the plant needs. Often when p and k are added in high quantities at the same time, one or the other remains unused in the medium. This can cause antagonism, chemical binding, and nutrient lockout. Peakboost contains organic acids that can help to adjust ph-down for your nutrient mixture. Peakboost is 100% soluble in water and doesn't leave residue in reservoirs and irrigation systems.
