Magnesium Deficiency in Cannabis
Introduction
Cultivating cannabis is a challenge regardless of whether you are new to growing or a seasoned expert. That’s why we’ve decided to offer our expertise in one of the areas cultivators struggle with most: magnesium deficiencies in cannabis.
Our post will cover how magnesium helps plant development, causes of deficiencies, identification, and treatment. Worry no longer if you are struggling with this issue because we’ve got you and your plants covered!
Magnesium’s Role in Cannabis
Magnesium is a naturally occurring mineral essential in the development, growth, and differentiation of cells in cannabis plants. Without magnesium, cells in leaves begin to die, which causes discoloration and withering.
Causes of Magnesium Deficiencies in Cannabis
Nutrient delivery is more complex than simply adding enough of a particular mineral to your grow medium. Therefore, there are multiple causes for magnesium deficiencies. We discuss them briefly below:
- Soil – Poor soil composition without enough magnesium-rich organic matter.
- Water – Overwatering, poor drainage, and using hard water affect how plants absorb nutrients.
- pH – High acidic conditions prevent cannabis plants from taking up enough magnesium.
- Nutrients – Insufficient or inconsistent feeding can lead to magnesium deficiencies.
How to Identify Magnesium Deficiency in Cannabis
Most worrisome conditions are visible through the plant’s appearance. Magnesium deficiencies are among the easiest to spot. You’ll notice your lower leaves becoming yellow and beginning to curl downwards.
In the early stages of magnesium deficiencies, the edges of your leaves will begin subtle yellowing around the edges. This is when you need to catch the problem; therefore, it's essential to regularly monitor your plants.
Prevention and Treatment
Prevention starts with using resilient genetics so plants can adjust to changes without losing leaves. However, the plant’s environment must be optimized to prevent magnesium deficiencies. Follow these three areas of cultivation best practices to ensure magnesium is being delivered to your plants.
- Soil amendments – Use high-quality, magnesium-rich fertilizers and ensure pH levels are in a specific range according to your strain’s preference.
- Water management – Practice proper irrigation techniques and regularly monitor water quality.
- Environmental control – Maintain temperature and humidity and ensure adequate ventilation. If your plants are stressed due to an inadequate environment, they won’t absorb nutrients.
Prevent Magnesium Deficiencies with Superior Genetics
While magnesium deficiencies are typically caused by growers failing to regulate their grow environment, all problems start with genetics. Resilient strains are less affected by soil, water, humidity, and temperature changes.
