Sensi Cal-Mag Xtra 10L – Calcium, Magnesium & Micronutrient Supplement

Correct Deficiencies & Strengthen Plant Structure With a Precise, Bioavailable Formula

Sensi Cal-Mag Xtra 10L is a premium calcium and magnesium supplement formulated to correct and prevent nutrient deficiencies that commonly occur in fast-growing plants—especially those grown in coco coir, RO (reverse osmosis) water, hydroponic systems, or under high-intensity lighting. Unlike basic Cal-Mag products, Sensi Cal-Mag Xtra includes additional iron, amino acids, and essential micronutrients, helping your plants maintain strong cell walls, consistent chlorophyll production, and healthy root and leaf development.

This formula uses highly bioavailable chelated minerals, allowing plants to absorb nutrients quickly and efficiently, even in systems where pH or EC levels fluctuate. It is ideal for preventing symptoms like leaf yellowing, interveinal chlorosis, weak stems, and stalled growth.

Key Features:

• Volume: 10L bottle – suitable for large gardens or repeated use

• Comprehensive Support: Provides calcium, magnesium, iron, and amino acids

• Chelated Micronutrients: Ensures rapid and efficient uptake at the root zone

• Prevents Common Deficiencies: Particularly useful for coco growers and RO-water users

• Improves Plant Strength: Supports cell structure, enzyme activity, and nutrient transport

• Versatile Application: Works in hydroponics, coco, and soil systems

• Compatibility: Can be used alongside all Advanced Nutrients base feeds

• 1 × 10L bottle of Sensi Cal-Mag Xtra

• Secure screw-cap with tamper-evident seal

• Printed feeding directions and safety information on the label

How to Use the Product & Best Usage Recommendations:

Dosage

• Apply 2 ml per litre of water

• Use as needed during vegetative and flowering stages, or as a corrective dose if deficiency symptoms appear

When to Use

• If using RO water

• When growing in coco, which naturally binds calcium and magnesium

• Under intense LED or HID lighting

• When plants show signs of Ca/Mg or iron deficiency (yellowing, pale new growth, weak tissue)

Application Tips

• Add Sensi Cal-Mag Xtra before adding base nutrients to ensure optimal mixing

• Suitable for all irrigation methods: hand-watering, hydro recirculating, run-to-waste, and autopots

• Monitor EC—Cal-Mag contributes to overall nutrient strength

• Can be used weekly as a preventative or for short periods as a corrective measure

• Shake very well before dosing to ensure even nutrient distribution

Best Recommendations

• Combine with a complete nutrient program for balanced feeding

• Avoid overuse; more is not better—stick to recommended strength

• In coco systems, use consistently throughout veg and early bloom for best results

• Maintain good pH stability to maximise the absorption of calcium and magnesium

Sensi Cal-Mag Xtra is ideal for growers looking to ensure strong structure, vibrant foliage, and trouble-free growth, especially in demanding hydroponic and coco environments.
