Kalix Magnesium (Soluble), 25 lb.

Kalix Magnesium is a fully water-soluble, hydroponics-ready magnesium fertilizer for growers who build or supplement their own feeding programs. This 25 lb bag dissolves cleanly for fertigation of soil and soilless crops, works in foliar applications, and serves as a component in the production of dry and liquid blends.

Magnesium sits at the center of every chlorophyll molecule, so adequate supply is essential for photosynthesis, deep green foliage, and steady growth; deficiency shows up quickly as interveinal yellowing on older leaves. A clean, single-ingredient soluble input that gives commercial growers and formulators precise control over magnesium levels in any system.
