Description
CANNA PK 13/14 is a concentrated phosphorus and potassium supplement designed to support plants during the peak flowering window—when demand for bloom nutrients typically rises and plants are focusing energy on building and finishing flowers.
Used alongside your normal base feed, it helps keep bloom nutrition on track at the point where plants often benefit from a targeted PK top-up. The result is a straightforward, reliable way to support flower formation, structure, and ripening without changing your whole feeding plan.
PK 13/14 is popular with growers running coco, hydro, and recirculating systems, and it also fits well into soil routines when used correctly. Because it’s highly concentrated, a little goes a long way—ideal for growers who want performance and consistency from a clean, easy-to-use additive.
