VitaLink CalMag 1L — Premium Ca/Mg with Chelated Iron

VitaLink CalMag 1L — Premium Calcium/Magnesium with Chelated Iron

VitaLink CalMag provides plants with precise levels of calcium and magnesium to stimulate healthy growth by increasing photosynthetic rate. The premium formulation also includes chelated iron to maximise the availability of macronutrients to your plants. Suitable for use across all hydroponic systems and grow media. The CalMag for growers who want broader benefit than basic Ca/Mg supplementation alone.

Why growers choose VitaLink CalMag:

• Precise Ca and Mg supplementation — addresses the most common deficiency combination
• Chelated iron included — broader micronutrient support than basic CalMag
• Increases photosynthetic rate — direct performance benefit beyond just deficiency prevention
• Maximises macronutrient availability — chelated form keeps nutrients bioavailable across pH range
• Works in all hydroponic systems — universal hydro compatibility
• Compatible with any growing medium — hydro, coco, soil all benefit
• Premium VitaLink formulation — UK-respected brand with proven track record

Who it's not for:

Check your tap water EC before ordering. UK tap water is often already hard (EC 0.6-0.8+) — if yours is, you don't need CalMag and over-supply creates other problems. Most useful for RO users, soft-water rural areas, or tap filtered through RO. For similar products at different price points: Canna CalMag, Athena CaMg, Dutch Pro CalMag, Shogun CalMag are alternatives. Not a base nutrient — it's a supplement.
