Iron Deficiency Expression
Iron deficiency expression in cannabis refers to the visual manifestation of inadequate iron availability to plants, characterized by chlorosis (yellowing) that typically appears first on newer growth while older leaves retain green coloration. This pattern occurs because iron is relatively immobile in plant tissues; when bioavailable iron is insufficient, the plant cannot efficiently translocate it to developing foliage. Iron deficiency can result from low soil iron concentration, high soil pH reducing iron solubility, poor root health, or nutrient antagonism from excessive calcium or manganese. Breeders and cultivators distinguish iron deficiency chlorosis from other nutrient deficiencies and stress responses to diagnose growing conditions accurately. Understanding this expression helps identify both environmental management issues and potential genetic susceptibility differences among

Breeders working in controlled environments monitor iron deficiency expression as an indicator of cultivar resilience and nutrient uptake efficiency. Selections showing chlorosis resistance or rapid recovery under iron-limited conditions may indicate stronger nutrient acquisition genetics, relevant for diverse growing substrates and pH ranges.
