Advanced Nutrients Sensi Cal-Mag Xtra 4-0-0

Advanced Nutrients Sensi Cal-Mag Xtra 4-0-0 is a fortified liquid plant supplement formulated to prevent and correct common calcium, magnesium, iron, manganese, and zinc deficiencies. Its chelated mineral blend helps keep essential elements available for efficient uptake while supporting healthy foliage, strong cell development, chlorophyll production, and overall plant vigor.

Sensi Cal-Mag Xtra also contains kelp-derived vitamins, minerals, and amino acids that support smooth plant processes and root-zone health. It is especially useful with reverse osmosis water, soft water, coco coir, or plants experiencing increased mineral demand.

Key Benefits:

• Corrects multiple deficiencies: Supplies calcium, magnesium, iron, manganese, and zinc in one formula.
• Chelated mineral sources: Helps keep essential elements available for efficient root absorption.
• Calcium support: Promotes strong cell walls, structural development, and healthy new growth.
• Magnesium support: Supports chlorophyll formation, photosynthesis, and plant metabolism.
• Chelated iron: Helps prevent iron lockout and deficiency-related yellowing, particularly in coco coir.
• Kelp fortification: Supplies naturally derived vitamins, minerals, and amino acids for added plant support.
• Full-cycle versatility: Suitable for use during vegetative growth, flowering, and fruit production when additional minerals are needed.
• Coco and RO-water support: Helps replace minerals that may be unavailable in coco or removed through water filtration.

Guaranteed Analysis and Formulation:

• N-P-K: 4-0-0
• Key minerals: Chelated calcium, magnesium, iron, manganese, and zinc
• Additional ingredients: Kelp-derived vitamins, minerals, and amino acids
• Product type: Liquid calcium, magnesium, and micronutrient supplement
• Application: Corrective or preventive root-zone feeding

How to Use:

• Correcting a Deficiency: Mix 2 mL per liter of water or nutrient solution. Repeat after one week if necessary.
• Regular Feeding Program: Apply 2 mL per liter and reassess plant response after one week.
• Per-Gallon Equivalent: Approximately 7.5 mL per gallon.
• RO or Soft Water: Use preventively at the recommended feeding-chart rate while monitoring EC, PPM, and pH.
• Coco Coir: Apply as needed to compensate for coco’s tendency to bind certain minerals, particularly iron.

Do not automatically increase the dosage when symptoms persist. Similar symptoms may result from nutrient lockout, improper pH, excessive EC, overwatering, poor drainage, or inadequate runoff.

Recommended Mixing Instructions:

1. Shake the bottle thoroughly before measuring.
2. Fill the reservoir or watering container with fresh water.
3. Add base nutrients according to their required mixing sequence.
4. Add Sensi Cal-Mag Xtra separately and mix thoroughly.
5. Add other compatible supplements individually, stirring between additions.
6. Check the final EC, PPM, and pH before feeding.

Never combine Sensi Cal-Mag Xtra directly with undiluted nutrient concentrates.

Using It With Other Advanced Nutrients Products:

Sensi Cal-Mag Xtra is compatible with Advanced Nutrients pH Perfect and non-pH Perfect base nutrients, as well as most other fertilizer programs. However, many Advanced Nutrients base formulas already contain calcium, magnesium, and essential micronutrients.

Use supplemental Cal-Mag when water quality, coco coir, plant demand, or visible symptoms indicate that additional minerals may be beneficial. Overapplication can raise EC or create an imbalance with other nutrients.

When deficiency symptoms appear despite adequate mineral levels, inspect irrigation frequency, runoff, root-zone pH, and input EC before increasing the application rate.

Growing Media and System Compatibility:

Sensi Cal-Mag Xtra is suitable for:

• Hydroponic reservoirs
• Coco coir
• Soilless growing media
• Aeroponics
• Deep water culture
• NFT systems
• Drip irrigation and emitters
• Flood-and-drain systems
• Regular-watering container applications

Important Usage Notes:

• Always shake well before use.
• Monitor plant response before repeating treatment.
• Avoid unnecessary Cal-Mag supplementation when the base fertilizer and source water already provide sufficient minerals.
• The manufacturer lists the product as foliar-compatible; follow the current bottle label for foliar dilution and application instructions.
• Store tightly sealed in a cool, dry location away from direct sunlight and extreme temperatures.
