Without the proper amount of nutrients and minerals, the plants won’t survive long. In the wild, they absorb all the useful things from the soil as it has got every mineral and chemical compound in it. When it comes to growing any plants yourself, especially cannabis, it is really important to pay attention to the minerals your plant needs.
Sometimes, we forget to pay attention to the symptoms that are being shown by the plant because of deficiencies like Magnesium. If you are observing something unusual with your cannabis plant, then it can be because of magnesium deficiency. Read this post till the end, as we have mentioned everything about cannabis magnesium deficiency and how you can easily fix this problem to make your plant healthy again.
Not only cannabis plants but Magnesium is required by every plant as it helps them in the photosynthesis process and in enzyme activation too. Magnesium is a vital nutrient for cannabis plants, and its deficiency can cause stunted growth, yellowing of leaves, and reduced yields.
It is important for growers to keep an eye on the magnesium levels in their plants and provide the necessary supplement to maintain healthy growth. Among all the nutrients, if Magnesium is lacking, then your plant will stop growing as it is required for the division and elongation of cells, which is essential for the growth and development of the plant.
So, always pay attention to the mineral levels of the soil.
If you know how to diagnose Magnesium deficiency and other issues related to the plants, then it becomes easier for you to fix the problem. Whenever a plant is not getting something in adequate amounts, it will start showing some symptoms.
The same goes for Magnesium deficiency, too, as when the plant is missing it, you will start noticing changes in the entire plant. Every person must know about the vital signs that a plant shows when there’s a deficiency of something as it becomes easier for them to get rid of the issue themselves. Below we have shared some major signs that indicate Magnesium deficiency in cannabis plants.
Yellowing of Leaves – The first and the earliest sign that a cannabis plant will show is the yellowing of the leaves, particularly between the veins. Among other minerals, Magnesium helps plants in generating a component named chlorophyll that gives the green colour to the leaves, and when it is lacking, the leaves will change their colour.
Stunted Growth – If your plant is above a few inches long, then you will notice that the growth of the plant has stopped. It is always recommended to have a check of the plant’s growth every week as it helps you in identifying the possible problems and in better development of the plant.
Interveinal Chlorosis – As we said above, when there’s not an adequate amount of chlorophyll in the plant, the leaves will start turning yellow, and the green colour will be restricted to the veins. Remember that the leaves won’t fall from the plant, but only their colour will change, but in some cases, the leaves will start falling off the plant.
Reduced Yield – Magnesium helps plants in forming new cells and buds. If your plant does not have the proper amount of Magnesium, then the overall yield of the plant will reduce automatically. Not only this, but if your plant already has some buds, then they will not mature, and you won’t get enough chemical compounds in them.
No New Leaves – Since your plant is not forming new cells and the entire photosynthesis process has stopped, the plant will not generate new leaves. Also, if the edges of the leaves have started curling upwards, then it is also a sign of Magnesium deficiency. It is very easy to diagnose the deficiencies of a plant, but the real game is in fixing the problem.
It is important to maintain the right balance of Magnesium in the soil or nutrient solution, as too much or too little can have negative effects on the plant’s growth and development. It is important to maintain the right balance of Magnesium in the soil or nutrient solution, as too much or too little can have negative effects on the plant’s growth and development.
If you think your plant is facing a Magnesium deficiency problem, then you can fix it yourself. There are a few things that you must know about if you are growing cannabis yourself. Read the important points mentioned below, as they will help you in keeping the right amount of Magnesium in the soil to ensure the plant grows appropriately.
- To fix a magnesium deficiency in cannabis plants, you can use a fertilizer that specifically contains Magnesium, such as Epsom salt, which can be added to the soil or mixed with water to create a foliar spray.
- Magnesium supplements like magnesium sulfate or magnesium oxide can be added directly to the soil to provide an extra boost of Magnesium.
- To ensure the plant can absorb the Magnesium, it’s important to test the pH of the soil and adjust it to the proper range between 6 and 7.
- Overwatering can cause Magnesium to leach out of the soil, so it’s important to monitor the water levels and make sure the soil is not too wet.
- Flushing the soil with water can also help remove any excess nutrients that may be preventing the plant from absorbing Magnesium.
NOTE: Do not add any type of product to the soil or spray on the plant unless you know about the ingredients it contains and their effects of it. Sometimes using artificial products can cause damage to the products, and you will not be able to revive the plant again. The Magnesium deficiency problem can be fixed easily, and you don’t have to worry about anything if your plant is facing this issue.
The methods mentioned above are quite enough to make a plant healthy again, so don’t worry about anything while following them. Also, you must wait for about a week or two since it takes some time for the plant to show effects.
Magnesium Toxicity – Magnesium toxicity, also known as “magnesium burn,” occurs when there is an excess of Magnesium in the plant’s environment. This can happen if the grower over-fertilizes with a fertilizer that contains high levels of Magnesium or if the pH of the soil is too high, making it difficult for the plant to absorb other nutrients.
Magnesium Deficiency – When the level of Magnesium goes below the recommended level in the plant’s soil, it starts affecting the plant’s growth and development. That is when it comes under Magnesium deficiency. We have already mentioned the signs and ways to get rid of this problem as it is very crucial to make the plant healthy again.
There are numerous ways to fix the Magnesium deficiency problem in plants, and the best one so far is adjusting the pH level of the soil, adding Magnesium-rich fertilizer, monitoring the water levels, and flushing the soil and planter with balanced water. Not only Magnesium but these solutions are useful to fix other problems as well.
It depends on the stage your cannabis plant is in. According to a recent study, it is suggested that you must maintain the level of potassium and calcium in the soil as they both can cause Magnesium lock-out. Also low pH level of the soil can also block the plant from absorbing important nutrients like Magnesium and Sulfur.
The length of time it takes for a cannabis plant to recover from a magnesium deficiency can vary depending on several factors, such as the severity of the deficiency, the stage of growth the plant is in, and the methods used to correct the deficiency. We will recommend you keep trying the methods to fix the problem for about two weeks.
Your cannabis plant will start showing deficiency signs, and that’s when you know something is wrong with the plant. It is important to keep an eye on the development and growth of the plant as it helps in the early detection of problems. We have already mentioned a few signs in this post, and you can read them to identify what the real problem is.
LED lights are known to generate less heat and UV radiation, which can reduce the need for additional cooling and UV protection. However, when it comes to Calcium and Magnesium are essential nutrients for plant growth regardless of the type of light used. Some lights may cause heating, and that’s when you need to put more nutrients in the soil.
So, this is all about cannabis Magnesium deficiency, and we hope you have found this post useful. Magnesium is not just another nutrient your plant need for growth, but it plays an important role in the development of new cells too. We have tried to mention everything related to it, and you might be able to understand its importance.
