Dutch Pro CalMag

Balanced calcium and magnesium for coco and RO water grows

Dutch Pro CalMag is a premium calcium and magnesium supplement that prevents and corrects the deficiencies that plague growers on RO water, soft water and coco coir. It supplies both elements in a readily available form to support strong root development, healthy foliage and improved nutrient uptake right through vegetative growth and bloom, keeping plants balanced and performing across hydroponics, coco and soil.

Key Benefits

• Prevents and corrects calcium and magnesium deficiencies before they stall the grow
• Stronger root development and healthier, more robust plant structure
• Improved nutrient uptake for faster, more vigorous growth
• Reduces blossom-end deficiencies and weak stems
• Ideal for RO water, soft water and coco, where Ca and Mg run short
• Compatible with most nutrient programmes across hydro, coco and soil

Yellowing leaves and weak stems from a calcium shortfall?

Calcium and magnesium shortages show up as slow growth, yellowing or interveinal leaves, weak stems and poor nutrient uptake, and they are most common in coco or on soft and purified water that starts out low in both. Dutch Pro CalMag restores the correct balance, building stronger roots and healthier foliage, cutting deficiency-related stress and supporting heavier flowering with better bud density.

How to Use

• Shake well before use.
• All media (veg and bloom): add 0.5-1ml per litre of water before adding your base nutrients, then mix thoroughly until fully dispersed.
• RO, soft water and coco: use throughout vegetative growth and the bloom stage, where Ca and Mg demand is highest.
• Monitor EC and adjust base nutrient strength as required.
• Do not exceed the recommended dose unless correcting a confirmed calcium or magnesium deficiency.
