Iron Deficiency
Iron deficiency in cannabis refers to a nutrient imbalance where plants cannot efficiently absorb or utilize iron, despite adequate soil concentration. This condition typically manifests as interveinal chlorosis—yellowing between leaf veins while veins remain green—beginning on newer growth. Iron deficiency occurs when soil pH is too high, microbial activity is disrupted, or when competing nutrients (calcium, magnesium, manganese) inhibit iron uptake. Breeders and cultivators track iron availability because severe deficiency stunts growth, reduces photosynthetic capacity, and can compromise final biomass. Understanding iron bioavailability is essential for both soil amendment protocols and selective breeding in diverse growing environments.

Breeders working in variable pH soils or hydroponic systems often select for cultivars demonstrating iron uptake efficiency and visual stress resilience. Genetic tolerance to iron-limited conditions helps producers maintain consistent yields across different cultivation substrates and water chemistry profiles.
