Understanding Nutrient Deficiencies in Cannabis: Insights from the Cannabis Business Times

The Cannabis Business Times, recently published an article discussing the complexities of distinguishing between potassium (K) and magnesium (Mg) deficiencies in cannabis plants.Both nutrients are vital for plant growth, but their deficiency symptoms often mimic each other, making it hard to confidently identify the issue. Potassium primarily affects water transport and sugar movement, with deficiencies showing up as yellowing on the edges of older leaves. Magnesium, essential for photosynthesis, causes interveinal chlorosis (yellowing between veins) in older leaves.

At Arvum Plant Labs, we see this challenge frequently in our tissue analysis work. Misdiagnosing K or Mg deficiencies can lead to unnecessary interventions or prolonged stress on the plants, reducing overall yields. Leaf tissue analysis is critical to understanding the actual nutrient status of your cannabis crop. By regularly analyzing leaf samples, growers can prevent or correct nutrient imbalances before they become visible and affect the plant’s growth.

The article also emphasizes the importance of keeping K and Mg within certain ranges in fertilizer solutions to prevent deficiencies, which mirrors our own recommendations based on years of tissue test data from cannabis growers.

Periodic tissue analysis can serve as a preventative measure, enabling growers to identify nutrient deficiencies before they become a problem. At Arvum Plant Labs, we specialize in helping cannabis cultivators fine-tune their nutrient regimens by providing accurate and timely tissue analysis results. This allows for proactive adjustments and more consistent, high-quality yields, avoiding costly mistakes in nutrient management.

The original article serves as a valuable resource for understanding these nuances, and we highly recommend reading it for anyone looking to deepen their understanding of nutrient management in cannabis.
