Calmag by Dutchpro is much more than a nutrient supplement; it is a highly concentrated solution meticulously designed to specifically address calcium and magnesium deficiencies that can negatively affect the development and health of cannabis plants.
These deficiencies can manifest in symptoms such as yellowing leaves, leaf deformities, or even growth arrest, compromising the quality and final yield of the harvest.

Discover excellence in plant nutrition with Dutchpro fertilizers, a reliable option to optimize the growth and development of your plants. Our outstanding product, the Dutchpro CALMAG fertilizer, is specially designed to address calcium and magnesium deficiencies in cannabis plants.
Magnesium, an essential component of the chlorophyll molecule, triggers photosynthesis, allowing leaves to efficiently absorb solar energy and produce the fundamental nutrients for healthy plant growth. With our highly concentrated formula, Dutchpro CALMAG treats and prevents these deficiencies, ensuring your plants reach their maximum growth potential.
To ensure optimal growth of your plants, it is essential to follow the dosage and instructions for use of CalMag Dutchpro:
Start in the Vegetative Phase: Start using CalMag from week 1 of the vegetative phase. The initial recommended dose is 0.4-4ML per application.
Continue in the Flowering Phase: Continue applying CalMag during week 1 of the flowering phase. Maintain the same dose used in the vegetative phase.
Continuous Use until the Flushing Stage: Continue using CalMag throughout the cultivation cycle, even up to the flushing stage, to ensure a constant supply of calcium and magnesium.
Recommendation with Additional CO2: It is especially recommended to use CalMag when additional CO2 is implemented in the growing environment, and CO2 PPM levels are above 1000 PPM. This supplement ensures optimal development of plants grown under these specific conditions.
The use of Dutchpro CalMag eliminates calcium and magnesium deficiencies, promoting healthy and vigorous growth in your plants. Follow these recommendations to maximize your crop results and ensure an abundant and high-quality harvest.
Dutchpro Calmag is a nutrient solution specially formulated with a high concentration of calcium and magnesium, essential nutrients for the healthy development of plants. These elements play fundamental roles in vital processes such as the formation of cell structure and the synthesis of chlorophyll, thus contributing to the vigor and vitality of plants.
In addition to its calcium and magnesium content, Dutchpro Calmag also contains nitrogen in its composition. Nitrogen is a key macronutrient that promotes photosynthesis by facilitating the production of chlorophyll, the pigment responsible for capturing light energy. Likewise, nitrogen promotes the synthesis of amino acids, which are precursors of essential enzymes for numerous metabolic reactions within the plant.
By combining the high concentration of calcium and magnesium with the presence of nitrogen, Dutchpro Calmag provides comprehensive nutritional support for optimal plant growth. This balanced formula ensures that plants have at their disposal the necessary nutrients to reach their maximum potential, promoting vigorous development and healthy production. Trust Dutchpro Calmag to meet the nutritional needs of your crops and achieve outstanding results.
