Nutrient Deficiency

Nutrient deficiency in cannabis cultivation refers to insufficient availability of essential macro- or micronutrients in growing media, resulting in visible plant stress symptoms. Common deficiencies include nitrogen (yellowing lower leaves), phosphorus (purple discoloration), potassium (brown leaf edges), and micronutrients like magnesium or iron (chlorosis). Symptoms vary by growth stage and severity, ranging from mild color changes to stunted development and reduced yields. Breeders and cultivators document nutrient deficiency responses as part of strain phenotype characterization, since genetic background influences how individual plants express nutrient stress. Accurate diagnosis requires soil testing, pH monitoring, and observation of symptom progression across the canopy.

Breeder relevance

Understanding how a strain's genetics influence nutrient uptake efficiency and deficiency expression helps breeders select for vigor and resilience. Commercial cultivators use deficiency tolerance data to inform feeding schedules and medium composition for specific cultivars.
