Calmag – Calcium & Magnesium 5 Liter | Bulk Ca\/Mg Support for Soil, Hydro & Coco<\/h1>\n

Calmag 5L<\/strong> is the cost-effective bulk<\/em> version of our Ca\/Mg supplement, designed for growers with multiple plants or continuous rounds. Calcium strengthens cell walls<\/strong> and supports root and shoot growth; magnesium forms the chlorophyll core<\/strong> and is essential for photosynthesis<\/strong> and sugar accumulation. Preventing and correcting<\/strong> Ca\/Mg deficiencies keeps your crop deep green, vital and resilient<\/strong>.<\/p>\n

What does Calmag 5L provide?<\/h2>\n

In systems with additional CO\u2082,<\/strong> in coco substrates or with very soft tap\/osmotic water, the Ca\/Mg requirement can be greatly increased. With Calmag 5L, you’ll keep stocked and can fine-tune weekly<\/strong> within your nutrition plan. This translates into uniform growth<\/strong>, stable leaf color and less risk of growth stagnation or leaf problems.<\/p>\n
