Terra Aquatica CalMag Supplement – GH CALiMAGic

Calcium and magnesium are a necessary part of growth for many plants, but that doesn’t mean they get as much as they need naturally.

Terra Aquatica CalMag Supplement provides the supplemental elements necessary to optimize plant nutrition and to prevent all-too-common problems. A concentrated blend of readily available calcium and magnesium, Terra Aquatica CalMag Supplement is a fully soluble product that won’t clog spray lines or drip emitters, and can easily be combined with fertilizers.

Mineral Magic

Calcium-intensive plants require higher levels of the mineral to thrive and avoid issues with growth and production. For instance, tomatoes that don’t have enough calcium develop blossom end rot, a common disorder producing blackened, soft indentations that mar and weaken the fruits.

Even if there’s enough calcium in the soil, it may be blocked from getting to the plant because the pH is too low. Or, plants that are prone to magnesium deficiencies, such as peppers, suffer from yellowish and drooping leaves along with reduced disease resistance from root to flower.

Terra Aquatica / GHE CalMag Supplement delivers the power of calcium and magnesium in a form that prevents secondary nutrient deficiencies and builds stronger plant structure.


Warning: Do not use with GHE soft water formulations, DualPart® Coco, or NovaMax®: they already contain enough calcium for even R.O. water systems.

Also, all GHE coco-coir products are pre-rinsed and stabilised; you can grow right from the bag without treatment.

For all other situations:

  • Use 1.5 ml per litre of water for most applications including organic and high demand crops.
  • With Reverse Osmosis, add 2ml per litre of water before adding nutrient solution.
  • When growing in Coconut Coir, using prepared soil or soilless mixes, or expanding compressed coco, use 1 to 1.5 ml per litre to wet (to saturation) the media, and then add to the nutrient solution at the same rate for the first two weeks. Continuous use may be helpful for fast-growing annuals.

Use GHE CalMag with:

  • Non -GHE nutrients, in hydroponics and outdoor gardening.
  • General Organics Thrive as needed if growing in coco-coir, especially non-GHE brand.
