Late Flower Discoloration
Late flower discoloration refers to color changes in cannabis foliage and calyxes that develop during late bloom stages, typically weeks 6–8+ of flowering. These shifts—from purple and blue to red, orange, or dark burgundy—result from anthocyanin and carotenoid pigment expression triggered by cooler temperatures, genetic predisposition, or nutrient dynamics. The trait is entirely phenotypic and does not indicate plant health problems or cannabinoid content. Breeders have selectively stabilized discoloration genetics in many modern cultivars, making it a documented trait in strain lineages. Documentation of this family aids growers in distinguishing natural color expression from disease or deficiency.

Breeders working in ornamental and connoisseur markets have isolated late-discoloration genetics to create visually distinctive phenotypes with stable expression. Crossing plants exhibiting strong anthocyanin or carotenoid production in late flower has become a deliberate strategy in strain development, often paired with other traits to maintain cannabinoid profiles.
