Phosphorus Potassium Ratios

Phosphorus-potassium (P-K) ratios refer to nutrient formulations rather than terpenes, but understanding these ratios is relevant to cannabis cultivation and secondary metabolite expression. Phosphorus supports flower development and terpene synthesis, while potassium regulates overall plant vigor and stress response. Breeders and cultivators working with specific genetics often adjust P-K ratios during flowering stages, as this can influence aromatic compound profiles in the final cultivar. However, P-K ratios do not directly determine terpene identity—genetic lineage remains the primary driver of terpene expression. This concept is better classified as a cultivation parameter than a chemical compound within the plant.

Breeders studying phenotypic expression across a lineage may document how different P-K feeding regimens affect volatile compound intensity in offspring, though this is an environmental factor rather than a heritable trait. Seed producers and growers tracking cultivar consistency often note P-K management as one variable influencing secondary metabolite profiles across harvests.
