Phosphorus and potassium become increasingly important during the flowering period. The aim of the flower is reproduction, a large amount of genes (DNA) is formed and this is accompanied by a high energy requirement. The phosphate is used as a building block.
Potassium is key to transporting water and nutrients from the roots to the leaves. It also controls CO2 absorption and has a significant influence on photosynthesis. From the middle of the flowering phase or when flowering noticeably decreases, Phosphorus Plus is given in combination with Bloom Complex. Why not before? Very simple: Before this point, it is not necessary, the PK concentrations from Bloom Complex are completely sufficient. Too high a P and K concentration would hinder the absorption of essential minerals or even lead to deficiency symptoms.
