Shogun CalMag – Calcium and Magnesium Supplement for Stronger Growth and Deficiency Control

Shogun CalMag is a concentrated calcium and magnesium supplement designed to prevent and correct common deficiencies in indoor growing.

It supports chlorophyll production, root development and overall plant structure, making it especially useful in coco coir, soft water areas and reverse osmosis setups where Ca and Mg levels are often low.

Key Benefits

  • Calcium and magnesium supplement; prevents and corrects common deficiencies
  • Optimised for coco; helps counter coco’s natural calcium draw
  • Improves nutrient uptake; supports better translocation within the plant
  • Boosts chlorophyll production; supports photosynthesis and healthy leaf colour
  • Supports root development; encourages faster, stronger root formation
  • Flexible use; suitable as a root feed or foliar spray across all media

Why You Need Shogun CalMag

Calcium and magnesium deficiencies are common in fast-growing plants, especially in coco, soft water areas or when using reverse osmosis.

These deficiencies can show as weak structure, poor leaf colour and reduced growth, limiting overall performance.

Shogun CalMag provides readily available calcium, magnesium and iron to support chlorophyll synthesis, enzyme activity and nutrient transport.

This helps maintain balanced feeding, stronger plant structure and more consistent growth across the full cycle.

How to Use Shogun CalMag

  • Add to your nutrient solution at 0.5 to 1ml per litre as a root feed.
  • Use alongside your base nutrients during vegetative growth and early flowering.
  • Increase use during periods of rapid growth or higher temperatures.
  • For foliar application, use at approximately 10 to 15ml per litre.
  • Adjust pH to around 6.0 for foliar spraying.
  • Apply regularly to maintain stable calcium and magnesium levels.

Top Tip

If you’re growing in coco or using low EC water, add Shogun CalMag from early stages rather than waiting for deficiencies to appear. Preventing issues is far easier than correcting them once they’ve developed.
