Iron Deficiency Chlorosis
Iron deficiency chlorosis is a physiological condition where cannabis plants exhibit yellowing of newer leaves while veins remain relatively green, indicating insufficient bioavailable iron despite soil presence. This occurs when soil pH is too high (typically above 7.5), nutrient lockout prevents iron uptake, or root systems are compromised by overwatering or pathogenic infection. The condition is commonly associated with hydroponic systems where pH management is critical, and containerized cultivation where soil chemistry shifts over time. Chlorosis progresses from new growth downward and can severely limit photosynthetic capacity if unaddressed. Growers distinguish iron deficiency from nitrogen deficiency by the vein-pattern retention and the affected leaf age. Recovery typically requires pH adjustment, improved drainage, or chelated iron supplementation depending on root health.

Breeders monitoring phenotypes under controlled cultivation conditions track iron deficiency chlorosis as an indicator of nutrient uptake efficiency and pH sensitivity. Strains showing resilience to iron lockout under high-pH conditions are valued in certain regional growing contexts, though this trait is managed through cultivation practice rather than genetic selection alone.
