Elevate your plant health and maximise yields with Shogun CalMag, the essential calcium and magnesium supplement meticulously formulated for superior nutrient uptake and robust plant development. Developed by leading biochemists, this powerful additive prevents and corrects common deficiencies, ensuring your plants thrive from vegetative growth through to flowering. Perfect for all growing media, especially coco coir, Shogun CalMag provides vital secondary macronutrients for unparalleled plant vigour.
Key Benefits of using Shogun CalMag
- Prevents & Corrects Deficiencies: Addresses critical calcium and magnesium shortages, which are crucial for strong cell walls and efficient photosynthesis.
- Enhances Nutrient Uptake: Improves the plant's ability to absorb and transport other essential nutrients, including phosphorus and potassium, throughout its structure.
- Boosts Chlorophyll Production: Supplies vital magnesium, a core component of chlorophyll, leading to greener foliage and accelerated photosynthesis.
- Strengthens Plant Structure: Calcium contributes to robust cell wall formation, providing increased resistance to environmental stresses and supporting heavier yields.
- Optimised for Coco Coir: Counteracts the cation exchange capacity of coco, ensuring ample calcium and magnesium are available to your plants where they are most needed.
- Contains Chelated Iron: Includes a trace amount of chelated iron to prevent common micronutrient deficiencies and promote vibrant, healthy growth.
- Versatile Application: Can be used as a root feed for ongoing prevention or as a fast-acting foliar spray to rapidly correct existing issues.
How to Use Shogun CalMag
Root Feed:
Add 1-2ml per litre to your nutrient reservoir or watering can. Use throughout the vegetative and flowering stages of growth. Cease use approximately two weeks before the final flush. This works synergistically with your base nutrients like Shogun Samurai Coco A & B or Shogun Samurai Terra Grow & Bloom.Foliar Application (for deficiency correction):Dilute at a rate of 10-15ml per litre of water. Spray directly onto leaves once per week until signs of deficiency are resolved. The ideal pH for a foliar spray is between 5 and 7. For best results, apply when lights are off to avoid leaf burn and allow sufficient drying time. Consider alternating with Shogun Geisha Foliar for enhanced flowering and overall plant health.Always add each nutrient, booster, or additive to your reservoir or feed water one at a time, stirring well before adding the next. For optimal results, ensure your pH is within the recommended range for your growing medium (e.g., pH 5.5-6.6 for coco/hydroponics, around 6.5 for soil).Can be used on all grow media including coco, hydroponics and soil.Available in 1 litre and 5 litres.Frequently Asked Questions
Do all plants always need additional Calmag supplements?
Not necessarily. While essential, some base nutrients already contain balanced amounts of calcium and magnesium. However, using treated water (like RO or distilled water) or growing in coco coir often necessitates supplementation. Shogun CalMag is designed to provide this vital balance, especially in modern growing setups and high-yield scenarios.Can you overdose on Calmag?
Yes, it is possible to over-supplement. Excess Calmag can lead to nutrient lockout, where plants struggle to absorb other critical nutrients like potassium or iron, and may even cause leaf tip burn or reduced growth. Always adhere to recommended dosage rates and monitor your plants for any signs of imbalance.When should I start feeding Calmag to my seedlings?
Seedlings generally require a gentle feed. Shogun CalMag is not typically necessary until your seedlings are established and have developed at least three sets of true leaves. For young plants, consider using a specialised product like Shogun Start which is specifically formulated for early growth.SKU: 1533 Free delivery on orders over £60*
