Nutrient Lockout
Nutrient lockout refers to a physiological condition in cannabis cultivation where plants cannot absorb available nutrients from the growing medium, despite adequate nutrient presence. This occurs when soil or substrate pH drifts outside optimal ranges (typically 6.0–7.0 for soil, 5.5–6.5 for hydroponics), or when excessive salts accumulate and block nutrient uptake pathways. The condition is often linked to overfeeding, poor water quality, or inadequate pH management rather than nutrient deficiency itself. Breeders and cultivators track genetic resilience to nutrient imbalances as part of phenotype stability research, though lockout is primarily an environmental cultivation issue rather than a heritable trait.

While nutrient lockout is not a genetic trait, breeders observe and document how different cultivars respond to suboptimal growing conditions and nutrient stress. Understanding a strain's resilience to pH fluctuation and salt accumulation helps cultivators optimize feeding schedules and medium choice.
