5 Ways to Cure Magnesium Deficiency in Cannabis

Cannabis San Bernardino

Magnesium deficiency is prevalent in marijuana plants. It tends to occur more often than other plant deficiencies, and that is why knowing its causes and treatment is vital. As the name suggests, magnesium deficiency is the lack of enough magnesium nutrients in your cannabis plants. In case you are wondering what that has to do with the development of your plants, you need to understand one thing. The availability of magnesium is essential in facilitating photosynthesis. That means lack of the nutrient will damage chlorophyll in your plants, and so they will not be able to absorb enough light for photosynthesis. If left unchecked, the lack of magnesium can lead to the death of the plant.

What Causes Magnesium Deficiency in Cannabis Plants?

Before taking a deep dive into the ways you can cure magnesium deficiency in cannabis, it is crucial to know what causes the problem. Among the common causes are the levels of other elements spiking more than the amount of magnesium. These nutrients can be ammonia or potassium. Also, it can be due to the roots being too shallow to absorb enough magnesium from the soil. Lastly, it may be due to high soil acidity. If the soil is too acidic, it is going to be hard for the cannabis plant to absorb the nutrients, and that will lead to magnesium deficiency.

How to Know the Plant Has Magnesium Deficiency

To know whether your cannabis plant is lacking magnesium, you need to look at the leaves. If you notice that the leaves are decolorizing, for instance, turning yellow then brown,  your cannabis plants lack adequate magnesium. The first leaves to suffer are usually the older ones and the ones close to the stalk. You must observe them first. While the plant is young, it may be quite hard to detect magnesium deficiency. That is because they tend to lack any visible signs.

Now that you know what magnesium deficiency is, what causes it, and the best way to identify the problem, you can have a look at five ways to deal with the situation. Note that you should be careful with your approach. That is because if the cause of magnesium deficiency to your cannabis plants is due to the acidity of the soil, then adding more magnesium to the soil can end up destroying your marijuana plants. Instead, take the approach below.

  1. Flush Marijuana Plants with Water That Has the Right pH

    If you find out that your soil has enough magnesium, but your plants lack the nutrients, it means that the roots of the plant are unable to absorb magnesium. You need to supply the cannabis plant with the nutrient manually. To do so, proceed by flushing the marijuana plants. First, prepare water that has the right amount of pH. In most cases, pH levels of 6.0 or 6.5 can do the trick. You can also flush them with neutral water or water with pH levels of 7.0. Doing so will see your plants absorb magnesium, and in no time, they will regain the ability to make their food through photosynthesis. Also, before buying indoor seeds, visit trusted dispensary sites for your trusted source of premium cannabis seeds.

  2. Supply the Soil with Essential Elements or Nutrients

    The best way you can cure magnesium deficiency in cannabis plants is to supply the soil with the vital elements that it lacks. The best way to do this is to use calcium-magnesium products. Mix 5ml of the product with roughly 3.8 liters of water then pour onto the plant. You should then wait and see if you notice any changes. If a week goes by without any distinct changes, you need to consider applying another method to save your cannabis plants.

  3. For Hydroponics, Transfer the Plant to Dolomite Lime Treated Soil

    If you’re applying a hydroponic method to growing your cannabis plants, you can make use of a dolomite lime solution. First, you need to mix the soil with dolomite lime. For excellent results, combine 3.8 litters of soil with approximately six spoons of dolomite lime. After you finish, give it a couple of days, then test to see if the pH value is neutral or slightly acidic with a pH of 6.5. If yes, transfer your cannabis plants to the prepared soil. They should be able to start improving within a couple of days.

  4. Use Epson Salt

    Another great solution to cure magnesium deficiency in marijuana is to use the Epson salt solution. The product works similarly to dolomite lime and calcium-magnesium. Proceed by mixing at least six spoons of Epson with 3.8 liters of soil. Test the pH after a few days, and if it is within the range of 6.5 to 7.0, then it is perfect. Transfer your plants to the treated soil, flush it with a solution of salt and wait for some days to see if you notice any changes.

  5. Sprinkle Magnesium-Sulfate Onto Your Plants

    As soon as you notice the cannabis plant’s leaves turning, get magnesium-sulfate from the store. You should then mix it with water to achieve a pH of 6.6 to 7.0. Once you confirm the pH, sprinkle the plants with the solution for a couple of days while observing any notable changes. The idea technique is to balance the pH of the soil and supply the plant with adequate nutrients. That will enable it to form chlorophyll and start absorbing sunlight, thus leading to photosynthesis. It is, by far, one of the easiest and common ways to deal with magnesium deficiency.

Each of the above approaches is effective in treating magnesium deficiency in plants. Ensure you don’t cut the decolorized leaves after treatment. Instead, use them to observe whether the treatment is working or not. In case it is working, you can go ahead and trim the affected leaves. Also, for high-quality germination, make sure you procure seeds from https://cbdfx.com/. The whole concept revolves around making sure the pH is perfect for the plant to be able to absorb magnesium so that it can make its own food.
