Nutrient Ratios

Nutrient ratios refer to the balance of macronutrients (nitrogen, phosphorus, potassium) and micronutrients (calcium, magnesium, sulfur, trace elements) in cannabis cultivation systems. While not terpenes themselves, nutrient ratios significantly influence terpene expression and overall plant chemistry during growth and flowering. Different genetic lines often exhibit distinct nutrient uptake patterns and sensitivities to deficiency or excess. Breeders and cultivators working with specific strain families have documented correlations between feeding protocols and the volatile aromatic profiles that emerge. Understanding strain-specific nutrient demands remains foundational for preserving genetic expression in seed production and clone work.

Breeders select for nutrient efficiency and uptake capacity when stabilizing lines, as nutrient stress—whether deficiency or imbalance—can suppress or alter terpene accumulation. Lineage records often note feeding protocols used during phenotype evaluation, helping breeders replicate chemotype consistency across generations and growing environments.
