Tips on How to Prevent and Fix Every Cannabis Nutrient Deficiency

The secret to great cannabis is no secret at all. The provision of suitable lighting and climate, the necessary amount of water, and nutrients are the main factors that contribute to the growth of healthy plants. Of course, there are some other things to keep in mind.

However, sometimes, despite all efforts, every breeder at least once faces a challenge: cannabis leaves turn yellow, what to do. But the problem may not be associated with any weed deficiencies or cannabis diseases. It’s just that the plant is not getting its required set of nutrients. It is stressed and becomes more susceptible to pests, rot, and fungus. Naturally, it is better to use high-yielding cannabis varieties with strong genetics. In this review, you will learn how to prevent and fix every cannabis nutrient deficiency.

Marijuana Diseases: Mobile and Immobile Substances

There is a classification according to which all nutrients are divided into two categories – mobile and immobile, depending on whether they can move after they have been fully absorbed by the plant and which type of substance is determined.

For example, lack of mobile substances will show symptoms in older leaves at the base of the plant. Signs of deficiency in immobile elements show up in newer growth on the upper and outer branches of the cannabis plant. Understanding how nutrients work will help diagnose cannabis problems.

Cannabis Leaf Diseases and Other Causes

Naturally, the yellowing and withering of cannabis leaves can be associated with more than just a deficiency or excess of nutrients. Unfortunately, not every cannabis crop grows without problems. This can be anything from manufacturer errors to invasive microorganisms. Even the best European growers who use Dutch marijuana seeds can run into problem plants. And yellow cannabis leaves are usually the first warning sign. 

Among the most common causes of yellowing and wilting of leaves, there are several factors such as:

  • Wrong watering. Cannabis plants will only thrive with an efficient watering cycle. Too much water can lead to root rot. A lack of moisture will stop growth. It is important to closely monitor the behavior of the plant after feeding, as well as keep a growth diary.
  • Light burns. Indoor cannabis plants under artificial lighting should be ideally positioned and the bulbs placed at the correct distance as per the manufacturer’s instructions. When lamps and reflectors are too close to flowering tops, buds and leaves will turn yellow and brown as the light is too intense. On the contrary, the lack of light leads to the fact that the lower leaves of hemp are already turning yellow, shaded, too far from the lamp.
  • Cold. At temperatures below 10°C, the leaves of most cannabis varieties turn yellow. It is important to avoid lower temperatures during the early growth stage.
  • Heat. Heatwaves can cause yellowing of the leaves of cannabis plants indoors and outdoors. Temperatures above 28°C prevent efficient photosynthesis of marijuana plants and cause buds to form looser and more airy. Indoor growers usually use an air conditioning system to avoid problems. And outdoors, the best gardeners can create a simple shade and hope the heatwave is short-lived.

Stick to the above recommendations and create ideal conditions to fix cannabis nutrient deficiency.
