Ultimate Cal-Mag

Ultimate Cal-Mag is a next-generation calcium and magnesium supplement designed to deliver clean, plant-available nutrition without the downsides of traditional formulations. Engineered with organic acid chelation and advanced pH buffering, it prevents nutrient lock-out, ensures compatibility in fertigation systems, and supports healthy, balanced growth without overstimulation.

Free from nitrogen and chloride, Ultimate Cal-Mag offers peace of mind for growers who demand precision and purity—whether in hydroponics, turf management, or commercial horticulture.

Key Features & Benefits

• Chelated with Organic Acids – Prevents calcium lock-out when used alongside phosphorus in soil or fertigation tanks.

• Zero Nitrogen Formula – Provides calcium and magnesium without pushing excessive vegetative growth, ideal during late flowering or for fine-tuned turf programs.

• Chloride-Free – Contains no hidden salts or toxic residues, even at higher application rates—superior to both budget and premium competitors.

• pH Buffered (5.5–6.0) – Formulated with the same intelligent buffering system as Liquid Gold, maintaining optimal pH range for nutrient uptake.

• Made in the UK – Precision-manufactured for professional growers under real-world growing conditions.
