Canna CalMag Agent — Ca/Mg Water Buffer

Canna CalMag Agent — Ca/Mg Water BufferCanna CalMag Agent Calcium Magnesium Buffer for Soft & RO Water A calcium and magnesium concentrate specifically for buffering soft or reverse osmosis (RO) water. Canna nutrients are designed to work optimally with water at EC 0. 4 0. 7; softer water lacks the Ca Mg required for proper nutrient uptake. CalMag Agent raises water EC to 0. 45 and supplies the Ca Mg your plants need. If your tap water is EC 0. 45 or higher, you typically don't need it.

Canna CalMag Agent — Calcium/Magnesium Buffer for Soft & RO Water

A calcium and magnesium concentrate specifically for buffering soft or reverse-osmosis (RO) water. Canna nutrients are designed to work optimally with water at EC 0.4-0.7; softer water lacks the Ca/Mg required for proper nutrient uptake. CalMag Agent raises water EC to 0.45 and supplies the Ca/Mg your plants need. If your tap water is EC 0.45 or higher, you typically don't need it.

Why growers choose Canna CalMag:

• Buffers soft and RO water — brings mineral content up to proper baseline for Canna nutrients
• Raises water EC to 0.45 — the target baseline Canna nutrients are designed for
• Supplies calcium and magnesium — the two macros most often missing in soft water
• Prevents deficiencies — Ca and Mg lockout symptoms (leaf spotting, tip burn) avoided
• Integrates with Canna feeding schedule — designed to work with Canna Aqua/Coco/Terra programmes
• Works with any nutrient brand — CalMag benefits aren't Canna-only
• Essential for RO-water growers — RO strips everything, you must re-add Ca/Mg

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 adding it can over-supply Ca/Mg. Most useful for RO users, soft-water rural areas, or tap filtered through reverse osmosis. Not a substitute for a complete feeding programme; it's a water buffer, not a nutrient.
