Mills CalMag

Supplement Ca and Mg to address mineral deficiency, promote growth and vitality, and stabilize EC. Also use to remineralise Reverse Osmosis water for great results.


Essential for soft water

CalMag is essential if you live in a soft water area – where your plants will suffer from lack of secondary nutrients.

Prevent deficiencies

Calcium and magnesium are the most common deficiencies in plants. Because calcium and magnesium are only effectively absorbed with pH > 6.3.

Maximized concentration

Mills Calmag is maximized in concentration, you’ll be surprised how long it lasts!

How it works.

A little Calmag goes a long way!

Calmag is highly concentrated. Use only approx. 1 ml per liter of water to increase the EC to the desired level.

To prevent calcium and magnesium deficiencies: give your plants 1ml per 1 liter of water without other additives with a pH of 6.5, 1x per week.
