Cal-Mag

Groindoor.com features some of the finest Cal-Mag supplements to ensure your plants never face a Calcium or Magnesium deficiency. 

What are Cal-Mag Supplements? 

Ideal for both hydroponic and soil-based plants, Cal-Mag supplements make sure plants never run short on Calcium and Magnesium. It is recommended that these supplements should be coupled with a rather regular feeding schedule. It is no different than how humans should consume multivitamins to ensure a healthy macronutrient and micronutrient uptake. 

Benefits of Cal-Mag 

  • Increases cell wall strength  
  • Improves nutrient absorption 
  • Enhances plant growth 
  • Increases metabolism by activating plant enzymes  
  • Improves flowering, budding, and fruiting 

As a grower, you should always make sure that your plant gets enough Calcium and Magnesium. If you do not notice any signs of a deficiency, using these supplements can be harmful, so make sure you use them according to your plants’ needs. In certain situations, such as when you are using reverse osmosis water or when using purified water, using Cal-Mag supplements becomes mandatory. The same is the case if you are growing in coco air. 

Should Cal-Mag be Used During Flowering? 

Experts believe it should not even be a question. Cal-Mag is absolutely necessary for plants during the flowering stage, and it should not be ignored if you want healthy and beautiful flowers. 

Can Cal-Mag be used in Soil? 

While Cal mag is to be used when growing in coco, is it really the best idea to use it in soil growing? The answer is Yes. Calcium and Magnesium are nutrients that all plants require regardless of the growing setup. 

How to spot calcium and magnesium deficiencies? 

Before we get started, you should check our complete article on diagnosing nutrient deficiencies. Here are a few basic things that will help you spot a Calcium and Magnesium deficiency: 

  • Stunted growth 
  • Unhealthy and spotted growth on the plant’s leaves  
  • Leaves lose their color, becoming light green and ultimately yellow 
  • Compromised plant health starting from the root system and making its way to the top of the plant.
