Dutch Pro CalMag 1L

If your plants are weak, get yellow leaves, thin stems or simply don't perform as they should – then they usually lack Calcium & Magnesium.
Dutch Pro CalMag provides exactly these two basic minerals in perfectly absorbable form.

The Woodpecker always uses CalMag when he wants to ensure absolute stability, growth strength and perfect nutrient absorption – whether in soil, coco or hydro.

No CalMag = No Power.
With CalMag = Rock-solid growth. 🪶💪

Stabilizes the entire nutrient system

With CalMag, your fertilizer schedule runs smoother, safer and error-free.

Application & Dosage

➡️ Recommended dosage:

0.5–1.5 ml per liter of water, depending on substrate & water hardness

➡️ Practice:

With RO water: ALWAYS use

With Coco: Weekly or with every watering

With LED Grows: Consumption is higher → give a little more

Can be used equally in Veggie & Bloom
