Cal-Mag

Looking for Cal Mag for plants? Look no further! Here are Hydrobuilder, we carry a wide selection of high-quality cal-mag supplements to help prevent nutrient deficiency in your plants, in this case being calcium and magnesium.

What is a cal mag supplement?

This blend of calcium and magnesium is an important one-two punch for both hydroponic and soil plants, and we encourage growers to utilize a Cal-Mag supplement in conjunction with a regular nutrient and feeding schedule, similar to how a human should take a multivitamin to ensure proper secondary macro-nutrient and micro-nutrient uptake.

What does Cal Mag do for your plants?

  • Increases strength of cell walls
  • Improves absorption of other nutrients
  • Increases growth rates
  • Activation of plant enzymes to aid metabolism
  • Increases flowering, budding, and fruiting

Before using one of these cal mag supplements, make sure your plant is actually deficient in either calcium or magnesium. There are certain situations where a grower should expect issues to arise and prepare accordingly, such as when using soft or purified water, as well as when using Reverse Osmosis water.

Another situation where Cal-Mag is necessary from the start is when growing in coco coir, as this medium tends to lock out calcium.

Can you use Cal Mag during flowering?

Yes, you can and SHOULD be using cal-mag during flowering. Calcium and magnesium are two super important nutrients for plants during the budding stage, and you need to make sure you are giving your ladies enough.

Can I use Cal Mag in soil?

We mentioned earlier that if you are growing in coco, you'll need to use cal mag. But what about cal mag for plants in soil?

To be honest, you still should be using cal mag to keep your plant healthy. These nutrients are essential to your plant, no matter where/how you grow.

What do calcium and magnesium deficiencies look like?

We have an entire article on diagnosing nutrient deficiencies in plants, but here are some of the things you should look out for if you think you may be deficient in calcium and/or magnesium:

  • A slow or halt in growth of plant and/or buds
  • Spotted, unhealthy growth on the leaves of the plant
  • Leaves start to turn a lighter green, and eventually yellow as issue persists
  • A gradual decrease in plant health, starting at bottom and working to the top

By identifying these issues early, a Cal Mag supplement can alleviate the symptoms and create a better nutritional balance in the plant, preventing health issues such as blossom end rot, stem rot, and tip burn.
