Mills Nutrients CalMag is a high-quality calcium and magnesium supplement developed to provide plants with two of the most important secondary nutrients required for healthy growth and development. Formulated as part of the Mills bio-mineral nutrient range, CalMag helps maintain balanced nutrition, prevent deficiencies, and support vigorous plant growth from propagation through to harvest.
Essential Calcium & Magnesium Support
Calcium and magnesium play vital roles in plant health and performance. Calcium contributes to cell wall strength, root development, and structural growth, while magnesium is a key component of chlorophyll and essential for efficient photosynthesis. Mills CalMag delivers these nutrients in highly available forms to support healthy plant function throughout the growing cycle.
Prevent Common Nutrient Deficiencies
Calcium and magnesium deficiencies are among the most common issues encountered by growers, particularly when using reverse osmosis water, soft water supplies, coco coir growing media, or intensive feeding programmes. Mills CalMag helps replenish these essential nutrients and maintain healthy, balanced plant growth.

Supports Healthy Plant Development
Balanced plant nutrition is essential for achieving vigorous growth and productive flowering. Mills CalMag helps ensure plants receive the support they need to maintain strong development, healthy metabolic function, and overall plant vitality throughout their lifecycle.
