Nutrient Deficiency Expression
Nutrient deficiency expression refers to the visible phenotypic symptoms plants display when lacking essential macro- or micronutrients—nitrogen, phosphorus, potassium, magnesium, calcium, iron, zinc, and others. These symptoms (leaf discoloration, stunted growth, interveinal chlorosis) vary by nutrient and plant genetics. Cannabis cultivars often show strain-specific vulnerability patterns; some lineages are known to flag deficiencies earlier or more visibly than others. Understanding deficiency expression is critical for breeders selecting for nutrient efficiency and resilience, and for cultivators optimizing feeding regimens across different genotypes.

Breeders working in resilience breeding use deficiency expression as a selection marker to identify vigorous lines with efficient nutrient uptake or tolerance to marginal growing conditions. Mapping deficiency phenotypes across a strain family helps breeders develop cultivars suited to specific soil types, hydroponic systems, or resource-constrained environments.
