KEY PH is a biological stimulant and pH regulator consisting of low molecular weight organic compounds with only highly acidified leaves. It helps to use active substances that are blocked at high pH. And also, PH can complex (chelate) and heal the assimilation nutrients and active substances contained in the same mixture. The assimilation of these organic acids by the plant strengthens the process of photosynthesis by bringing most of the necessary energy to the plant thanks to these organic components, which are easily assimilated with leaves.
