Magnesium Deficiency Interveinal Chlorosis
Interveinal chlorosis—yellowing between leaf veins while veins remain green—is a visual marker commonly associated with magnesium (Mg) deficiency in cannabis cultivation. This classification describes a nutrient-related phenotype rather than a genetic trait, appearing first on lower, older foliage before potentially progressing upward. Magnesium is a central component of chlorophyll molecules, so insufficient bioavailable Mg disrupts photosynthetic capacity. Breeders and cultivators monitor this symptom as an indicator of nutrient management rather than plant genetics, though some cultivars may express faster or slower visual responses depending on their vigor and uptake efficiency.

While not a heritable trait, recognizing interveinal chlorosis helps breeders evaluate nutrient uptake efficiency in candidate lines and growing protocols. Cultivators working with specific genetics may note differential sensitivity to Mg availability, informing feeding schedules and substrate selection during breeding trials.
