Source of Calcium

Calcium is crucial for cell wall formation in plants. Inadequate levels of calcium can lead to withered and stunted growth. When using additional nutrients to boost yield size, plants require even higher amounts of calcium to support the structural integrity of stems and leaves. Calcium also plays a role in regulating temperature and humidity stress, allowing proper functioning of stomata for gas exchange and transpiration.


Supplies Vital Magnesium

Magnesium is another secondary macronutrient necessary for chlorophyll production and photosynthesis. Plants grown under powerful lights, such as LEDs and HPS lights, require adequate levels of magnesium to support rapid growth and the development of large fruits and flowers.


Invaluable in Coco

Coco coir is a popular substrate choice for its high aeration, which promotes root network expansion. However, coco has a high cation exchange capacity and tends to bind to calcium and magnesium, making it challenging for plants to access these nutrients. Supplementing with a Cal-Mag product like SHOGUN Cal-Mag ensures that plants receive sufficient calcium and magnesium to thrive in coco coir.


How to Use SHOGUN Cal-Mag

  • Use SHOGUN Cal-Mag preventatively throughout the vegetative and flowering stages.

  • Add 1-2ml per litre of water to your hydroponic tank, reservoir, or watering system. Adjust watering frequency based on the needs of your plants and growing medium.

  • Discontinue use of SHOGUN Cal-Mag two weeks before the end of the plant's life cycle.

  • To address existing deficiencies, SHOGUN Cal-Mag can be used as a foliar spray. Dilute 15ml per litre of water and spray directly onto leaves once a week until signs of deficiencies are no longer present. Maintain a pH level between 5 and 7 for the foliar spray.


When to Use SHOGUN Cal-Mag

  • It is recommended to use SHOGUN Cal-Mag when growing in coco coir due to the substrate's tendency to bind to calcium and magnesium.

  • It can also be used in any substrate if calcium or magnesium levels are low, and signs of deficiencies are observed.


Why Choose SHOGUN Cal-Mag

  • It serves as a source of calcium, nitrogen, and magnesium to address and prevent deficiencies.

  • Boosts chlorophyll production and supports overall plant health.

  • Can be used as both a foliar and root spray for flexible application.

  • Essential in porous substrates like coco coir to ensure plants receive adequate calcium and magnesium.
