Feeding Sensitivity

Feeding sensitivity refers to a strain's observed responsiveness to nutrient concentration levels during cultivation. Plants classified as feeding-sensitive typically exhibit visible stress responses—such as nutrient burn, deficiency symptoms, or stunted growth—when nutrient ratios deviate from narrow optimal ranges. This classification is often documented in lineage records where breeders note cultivar behavior under standardized feeding protocols. Feeding sensitivity can result from genetic predisposition, selective breeding for specific cannabinoid or terpene profiles, or complex interactions between parent genetics. Understanding a strain's feeding sensitivity profile is relevant for growers planning nutrient schedules and managing input costs across production cycles.

Breeders working with feeding-sensitive lines must maintain detailed cultivation records to stabilize the trait across generations. Crosses between feeding-sensitive and more robust genetic backgrounds are sometimes employed to develop hybrids with improved nutrient flexibility while preserving desired secondary traits.
