We often focus on the main nutrients, but your plants will never reach their full potential without a solid backbone. Shogun CalMag provides a rich, optimised source of the two most critical secondary nutrients: Calcium and Magnesium.
Think of this as the "bodybuilder" supplement for your indoor jungle. It doesn't just cure yellowing leaves; it thickens cell walls, strengthens stems, and ensures your prized Aroids have the structural integrity to support massive foliage.
The Green Machine (Magnesium): Magnesium is the central atom of chlorophyll. Without it, your plants cannot photosynthesize effectively, rendering your expensive grow lights useless. Shogun CalMag keeps photosynthesis running at full speed, keeping leaves lush and green.
Built Tough (Calcium): Calcium aids in the thickening of cell walls. This creates visibly thicker stems and stronger branches, improving nutrient transport and making your plants more resilient against pests and environmental stress.
Essential for Coco Coir: If you grow in Coco Coir or semi-hydro, this bottle is non-negotiable. Coco coir naturally "locks up" calcium, stealing it from your plants. This supplement replenishes those levels to prevent early deficiencies.
Complete Balance: Unlike basic supplements, Shogun includes Nitrogen (2.6%) to aid uptake and Chelated Iron (0.1%) to prevent micro-deficiencies that often accompany Calcium issues.
Root Feed (Maintenance): Use 0.5ml – 1ml per litre throughout active growth. This is key for preventing issues before they start.
Root Feed (Deficiency): If you see rusty spots or yellowing between veins, increase the dose to 1ml – 2ml per litre to correct the imbalance.
Foliar Spray (Emergency Fix): For rapid results, you can use CalMag as a foliar spray. Mix 15ml per litre and spray the leaves just before your lights go off (or at sunset) once a week until the problem is resolved.
Nitrogen: 2.6%
Calcium: 3.2%
Magnesium: 1.2%
Iron: 0.1%
Available Sizes: 250ml, 1L, and 10L
