Ph Dependent Lockout
pH-dependent lockout refers to a condition where cannabis plants cannot access certain nutrients despite their presence in the growing medium, due to unfavorable pH levels. This phenomenon occurs across hydroponic, soil, and soilless systems when pH drifts outside optimal ranges—typically 6.0–7.0 for soil and 5.5–6.5 for hydro—preventing nutrient uptake at the root zone. Breeders and cultivators document this as an environmental management challenge rather than a genetic trait, though plant robustness against pH fluctuation varies among cultivars. Understanding pH-dependent lockout is essential for maintaining plant health, as the condition can mimic nutrient deficiencies visually but requires pH correction, not nutrient supplementation, for resolution.

Breeders working toward resilience in diverse growing systems often select for cultivars showing consistent nutrient uptake across wider pH ranges. This trait is studied indirectly through phenotype stability testing across different cultivation environments.
