Core A

Prescription Blend Core A is the foundational Part A base nutrient from Prescription Blend's analytically formulated cannabis nutrient system. The Core provides the mineral foundation of the complete program — calcium, nitrogen, trace elements, and the supporting minerals that must be separated from Part B's phosphate and potassium in the two-part format.

Prescription Blend's analytical approach means Core A's formulation is based on actual cannabis nutritional demand data rather than generic plant nutrition models, creating a more precisely calibrated nutrient solution for cannabis-specific applications.

Use alongside Core B throughout the grow cycle per Prescription Blend's feeding schedule. Compatible with all growing media. Made by Prescription Blend.
