Dutch Pro Calmag is a professional-grade calcium and magnesium supplement formulated to provide plants with two of the most important secondary nutrients required for healthy growth and development. Developed to work alongside the Dutch Pro 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. Calcium supports strong cell walls, healthy root development, and structural growth, whilst magnesium is a key component of chlorophyll and is essential for efficient photosynthesis. Dutch Pro 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 nutritional issues faced by growers, particularly when using soft water, reverse osmosis water, coco coir, or intensive feeding programmes. Dutch Pro Calmag helps replenish these vital elements and maintain balanced plant nutrition.
Key Benefits
- Provides readily available calcium and magnesium
- Helps prevent nutrient deficiencies
- Supports healthy root development
- Promotes stronger stems and plant structure
- Encourages healthy green foliage

Supports Healthy Plant Growth
Balanced levels of calcium and magnesium are essential for vigorous growth and healthy plant development. Dutch Pro Calmag helps plants maintain optimal nutrient levels, supporting healthy metabolism, stronger growth rates, and improved overall crop performance.
Perfect For Coco & Soft Water Growing
Coco coir naturally binds calcium and magnesium, whilst soft water and RO water often contain insufficient levels of these nutrients. Dutch Pro Calmag helps compensate for these deficiencies, making it an ideal supplement for modern cultivation systems.
Improves Nutrient Efficiency
When calcium and magnesium levels are balanced, plants are able to utilise other nutrients more effectively. Dutch Pro Calmag helps improve nutrient transport and uptake, contributing to healthier plants and more efficient feeding programmes.
Suitable Throughout The Entire Growing Cycle
Dutch Pro Calmag can be used during propagation, vegetative growth, and flowering whenever additional calcium and magnesium supplementation is required. Its versatile formula makes it ideal for both preventative use and correcting emerging deficiencies.
