Plants have an increased need for phosphorus and potassium in the flowering phase. By applying PK 13/14 we completely fulfil this need.
The flowering phase is the supreme point in the life of the plant when the metabolism is working at full power and large quantities of enzymes are being produced for flowering.
PK 13/14 should be used starting from the second half of the flowering phase up to one week before the end of the cycle.
