Deficiency of Nitrogen in Cannabis

What does nitrogen have to do with cannabis cultivation? When a cannabis plant has a nitrogen deficiency, it becomes vulnerable to pests, viruses, viroids, molds, and other harmful factors. Without nitrogen, cannabis plants cannot produce energy, leaving them vulnerable. When it comes to learning about cannabis, Verne Bio is on your side.

  2. When we think of nutrients required by cannabis plants, we often think of calcium, magnesium, and potassium. However, cannabis plants also require nitrogen to grow successfully. This vital nutrient is just one of many needed to produce high yielding, high quality crops. What is Nitrogen? Nitrogen is one of the most abundantly found elements in the world. According to Britannica, “About four-fifths of Earth’s atmosphere is nitrogen, which was isolated and recognized as a specific substance during early investigations of the air.” Nitrogen is also an essential nutrient plants require to grow, including cannabis. However, it does need to be supplied regularly to keep your cannabis crop healthy and happy. According to Utah State Extension, “Nitrogen is highly soluble and easily washed from soils and therefore must be replaced regularly, especially during vegetative plant growth.”

  3. How Does Nitrogen Impact Cannabis? What does nitrogen have to do with cannabis cultivation? It’s a valid thing to wonder. After all, nitrogen is typically something that occurs naturally in the air and the soil. However, it is one of the main nutrients required by cannabis plants. According to Koch, “Nitrogen is also a component of the chlorophyll molecule, which enables the plant to capture sunlight energy by photosynthesis, driving plant growth”. This means that when a plant does not get enough nitrogen in its feeding regime, it cannot produce the energy it needs to grow and produce a healthy or weighty harvest. What happens when a Cannabis Plant has a Nitrogen Deficiency When a cannabis plant has a nitrogen deficiency, it becomes vulnerable to pests, viruses, viroids, molds, and other harmful factors. Without nitrogen, cannabis plants cannot produce energy, leaving them vulnerable. This vulnerability can lead to a cascade of other problems that result in harvest yield reduction and in some cases even the death of the plant. In a 2020 research article published by Frontiers in Plant Science, researchers noted growth retardation in cannabis plants with a low nitrogen supply. According to their findings, “the morpho-physiological function under long photoperiod in medical cannabis is optimal at 160 mgL−1 N supply, and significantly lower under 30 mgL−1 N, with visual deficiency symptoms, and 75 and 25% reduction in plant biomass and photosynthesis rate, respectively.”

  4. How to Spot a Nitrogen Deficiency Photo by Markus Winkler on Unsplash When a cannabis plant has a nitrogen deficiency, it displays multiple symptoms. In both vegetative and flowering plants, the leaves will lose their luster and begin to turn yellow. As the deficiency progresses, the leaves will begin to drop, creating an ideal environment for pests if left in the pots and on the tables.

  5. In flowering plants, plants with a nitrogen deficiency will flower prematurely. However, the overall crop will produce a low yield. This unnecessary stress on your impacted cannabis crop can lead to herming (the process by which female cannabis plants develop male attributes). If left untreated, the pollen sacs on the hermed plants will spread to previously unaffected plants, escalating the problem. Nitrogen deficiencies can be combated by adding more nitrogen to the soil or soil alternative. Depending on how the plants are being fed, the nutrient line being fed to the plants can be adjusted to include more nitrogen. However, for live soil and similar options, fertilizer or other naturally nitrogen-rich compost items may be an option. Where to Learn More Ready to keep expanding your knowledge about cannabis?
