Marijuana Nutrient Magnesium: Deficiency & Prevention

Nutrients are necessary for Marijuana plants the same way humans require essential nutrients to thrive. The marijuana plant requires a variety of critical nutrients, especially macro and micronutrients. The pH in the nutrient-water solution is critical for maintaining the health of your marijuana plants. Nutrient deficiencies in the marijuana plants, including potassium, zinc, magnesium, iron, calcium, protein, have been observed.

The necessity for magnesium in plants is very important. It is also required for photosynthesis. Leaves are unable to absorb and convert light into energy without photosynthesis. Even though they receive the proper quantity of light, vegetation with a magnesium deficit will gradually starve to death.

Keeping an eye on the pH level of the nutrition-water mix will help you prevent nutrient deficits. Such nutrients are not being absorbed, which is why your plant is lacking in them. Improper levels will prevent some nutrients from being absorbed, resulting in negative consequences. If you give your plants their nutrients on a regular basis, it’s likely that perhaps the pH is just too high or too low, and also, the plant isn’t absorbing them.

We’ll go over everything you need to know about the magnesium marijuana nutrient in this article. Continue reading to learn more.

What Is Magnesium?

Magnesium is a chemical substance that, in the situation of the Marijuana plant, functions as a basic nutrient that must be available throughout all phases of the plant’s lifecycle and abundantly, however with control over it.

Magnesium is the most abundant element in chlorophyll and has been required for plants to absorb sunlight efficiently. It also has the ability to neutralize chemicals, as well as the hormones produced by the plant, which serves as an activator.

The Marijuana plant consumes magnesium differently based on the foundation inside the soil, so it’s critical to strike the right balance in between magnesium which the plant takes out from soil or ground inside the pots, and also the magnesium that’s absent, which we’ll have to supplement manually using various approaches.

In this way, rather than controlling magnesium levels, another very typical problem you may encounter in a marijuana plant is a shortage of magnesium or, to a smaller extent, an excess in magnesium.

How Can Magnesium Deficiency Be Recognized?

Chlorosis occurs in plants due to a lack of chlorophyll. As time goes on, it will wipe off on the lower leaves, causing brown spots to form upon on plant’s roots, tips, or leaf edges. The tips that are affected by this occurrence coil up and slowly die. This affects the plant, making nutrient absorption, particularly magnesium absorption, far more difficult. If that’s not treated in a timely manner, the entire plant may change color and die.

Perhaps the most obvious indicator of magnesium deficiency among marijuana plants is a troubling fading of green to light green and yellow on the leaves. Chlorosis is the medical term for this. Chlorosis appears first along the borders and between the vein upon leaves, instead of all around them or from roots outwards or ends inwards, as other diseases do.

The oldest, as well as closest leaves at the base of the plant, should be the first to reveal these symptoms. This is due to the plant removing magnesium from all these leaves in order to send it all to the newer ones and in order to survive.

The most common blunder made by new gardeners is attempting to apply a temporary remedy by boosting nutrient dosage. In addition, it will very certainly result in a nutritional lockout. Yellow leaves as well as brown blotches on the bottom of the plant, regardless of development stage or medium, are just a red warning for magnesium shortage. Micronutrient deficiencies, including magnesium insufficiency, typically begin in the root system.

How To Cure Magnesium Deficiency In Marijuana Plants?

Without tests performed, testing magnesium levels in a substrate are hard, and only a few experts have ready access to it. Therefore, instead of attempting to change one issue at a time, the best strategy would be to fix everything that could have created issues.

1.    Remove Excess Nutrient Build Up

A complete flush using pH-balanced water followed with another flush using pH-balanced water mixed with regular marijuana fertilizers is perhaps the most popular technique to regulate pH and help remove nutrient development in non-soil substrates, including such coco coir or in a hydroponics way. For optimal magnesium absorption in hydroelectric systems, the level of pH must be around 6.0–6.5.

2.    Use Magnesium Foliar Spray

Making a foliar spray using magnesium sulfate and water is often very effective. Magnesium sulfate, sometimes known as Epsom salts, is widely available online and also in huge pharmacies.

Mix one spoonful of Epsom salts with two liters of water to make a magnesium foliar spray. That mixture would then be sprayed onto plants every three days, followed by a ten-day freshwater spray to ensure no residue builds up upon the leaves.

3.    Grow Your Marijuana In Soil

Growing marijuana plants in soil, specifically in the open fields instead of pots, reduces the risk of magnesium deficiency significantly. This is because the plants will be able to pick up natural magnesium from the soil.

However, growing cannabis plants in the soil do not ensure immunity! The pH of soil must be between 6.0 and 7.0. The same flushing approach as mentioned above can be used, followed by the addition of specialized magnesium as well as calcium supplements

Final Thoughts

Magnesium insufficiency is a common cause of marijuana stunting. This is a deficiency that no farmer wants, whether it occurs early throughout the vegetative growth process or later in the flowering stage.

Magnesium deficiency could be prevented and healed using the information provided above. Thus, every grower should be able to recognize when their plants become unwell. They must be able to look at their crops or plants and tell exactly what is wrong with them at a single glance. The above-written article mentions all the information about how one must know to prevent magnesium deficiency in their marijuana plant.
