Macro Nutrient Ratios
Macro nutrient ratios describe the relative proportions of nitrogen (N), phosphorus (P), and potassium (K) in cannabis cultivation media and fertilizers, commonly abbreviated as NPK values. These ratios are foundational to plant development cycles—vegetative growth typically benefits from higher nitrogen, while flowering phases often require elevated phosphorus and potassium. Understanding macro nutrient balance is critical for breeding programs, as nutritional stress during plant development can influence cannabinoid expression, terpene profiles, and phenotypic stability across generations. Lineage records frequently document nutrient regimens alongside environmental conditions, recognizing that consistent feeding protocols contribute to reproducible trait expression.

Breeders working in controlled environments use standardized NPK ratios to isolate genetic traits from nutritional variables, ensuring that phenotypic differences observed in offspring reflect true genetic variation rather than nutrient-driven environmental modification. Consistent macro nutrient management across breeding populations strengthens the reliability of selection criteria and stabilize
