Mineral-Calmag is an ultra-clean, pH stable, high-performance calcium & magnesium supplement for indoor and outdoor cultivation. Mineral-Calmag is compatible with all base nutrients and will last a minimum of 14 days in a nutrient tank or reservoir with no signs of degradation.

Key Ingredients

Nitrogen: Crucial element in chlorophyll, crucial component of plant amino acids.
Calcium: Integral structural element to plant cells.
Magnesium: Central element in the formation of chlorophyll, source of photosynthetic activity, enzymatic process activator.

What is Mineral-CalMag?

MINERAL-CALMAG is a 100% water-soluble additive containing necessary plant-available forms of nitrogen, calcium and magnesium.

This formulation has been designed to prevent common deficiencies while buffering your feed water when growing in soil-less mediums such as coco, perlite, rockwool, hydroton or recirculating systems and/or using filtered sources of water. MINERAL-CALMAG can be used throughout the entirety of the vegetative and flowering stages of growth.

MINERAL-CALMAG has excellent pH stabilizing capabilities and is the calmag of choice for commercial growers or any cultivator operating fertigation systems, recirculating systems or longer reservoirs.

Why use Mineral-CalMag?

Concentrated and easy to use dilutions of just 1.5 ml per 1 gallon.
Utilizes the highest grade raw minerals available providing the absolute cleanest possible calcium & magnesium additive for your cultivation system.
Prevents coconut-fibre based planting mediums from becoming a source of nutritional imbalance, lending stability to your crops’ flowering stage of growth.
Replaces the calcium ions lost through constant irrigation that occurs during indoor cultivation practices.

How To Use Mineral-CalMag

Shake well before use. If using FASiLITOR, ensure FASiLITOR is mixed first. Add MINERAL-CALMAG second, mix well, then add the remainder of your products.

In soil: Use once a week

In coco/soil-less/hydro: Use in combination with APTUS BASE every watering. Do not use any additional non-APTUS sources of phosphorus.

Mineral-CalMag Education

Through high-intensity irrigation methods often seen in modern indoor cultivation practices, coconut-fibre based planting mediums can become deficient of calcium resulting in high levels of accumulated potassium and sodium. This excess of potassium and sodium most often results in antagonism and lockout, leading to deficiencies within the plant.

Due to the mixture of nutrients coming into the plant being fully optimized for healthy growth, allowances for varying excess of potassium and sodium are not considered. Because of this, mineral antagonism occurs, preventing the uptake of magnesium, causing unhealthy growth and the appearance of deficiencies.

MINERAL-CALMAG replaces the calcium ions lost through constant irrigation, providing the buffering capabilities needed to prevent this antagonistic exchange.

Tips from the field

MINERAL-CALMAG is required when using BASE. If you use BASE, ensure you use MINERAL-CALMAG or MASSBOOST to avoid deficiencies. BASE contains zero calcium and must be used in conjunction with MINERAL-CALMAG or MASSBOOST.

When mixing your nutrients, be careful to avoid adding phosphorus supplements like PEAKBOOST directly onto MINERAL-CALMAG without mixing well. Always add and stir each product before adding the next to minimize local fallout which can decrease the quality of your nutrient mix.

During weeks where a high number of products are used, your available amount of nitrogen can get high. If you are not using BASE, and are using a 2 or 3-part base nutrient, you may want to consider decreasing the part containing nitrogen by 10 – 20%.
