What Ionic Cal-Mag Pro Does

Ionic Cal-Mag Pro has been designed to provide an extra supply of calcium and magnesium, two essential secondary elements for strong cell walls, efficient photosynthesis and proper nutrient uptake. Adding this product to your feeding schedule helps prevent common issues such as mid-cycle growth slowdown, interveinal yellowing, necrotic spots caused by calcium deficiency and general lack of vigor, especially during flowering.

The addition of chelated iron, amino acids and humic acids further enhances nutrient availability, supports chlorophyll production and helps the plant overcome stress factors (environment changes, heavy PK boosters, irregular irrigation, etc.).

Benefits for Cultivation

• Prevents and quickly corrects Calcium and Magnesium deficiencies
• Reduces leaf yellowing, chlorosis and spotting
• Improves vigor, strength and tissue development
• Enhances the absorption of base fertilizers and PK boosters
• Ideal for coco substrates, which tend to bind calcium
• Perfect for soft or reverse-osmosis water low in minerals
• Suitable for all plant species in soil, coco or hydro

Dosage & Directions

• Prevention: 0.5 ml per liter of water (0.5 ml/L) as part of your regular feeding.
• Existing deficiencies: 1 ml per liter of water (1 ml/L) until plants fully recover.
• Frequency: follow your usual irrigation schedule; typically 1–2 times per week depending on crop and substrate.
• Compatibility: use together with a complete base nutrient (Ionic or other quality fertilizers).

Shake well before use. Add Ionic Cal-Mag Pro after mixing your base nutrients, then stir thoroughly. Always check and adjust pH and EC after mixing. Do not exceed the recommended doses on the label.

When It’s Especially Useful

• Coco cultivation, where the substrate can retain calcium
• Heavy use of PK boosters, which may induce Ca/Mg lockout
• Very soft water or reverse-osmosis systems
• High-intensity indoor environments (LED/HPS)
• Plants showing interveinal yellowing, dark spots or slow growth

Final Note

Ionic Cal-Mag Pro does not replace your base fertilizer — it completes it, ensuring your plants always have the right amount of calcium and magnesium to express their full potential in growth and quality.
