Canna PK13/14

Canna PK13/14 is a late flowering booster designed to pack on extra weight in the weeks prior to harvest. P and K are the chemical symbols for phosphorous and potassium the two key elements a plant needs during the flowering cycle. Your base nutrient provides standard levels of PK but what PK13/14 does is provide a larger dose when your plants need it most to enable the development of larger flowers and fruit.
