Visual Symptoms and Leaf Analysis
Calcium deficiency in cannabis plants often manifests visibly, particularly on the leaves. In the earliest stages, the plant leaves might show signs of marginal yellowing, initially appearing at the leaf tips and progressing inward. As the deficiency worsens, you may notice the leaves curling upward and developing a crinkled or distorted appearance https://kindseed.com/cheap-seeds/
Severe calcium deficiency leads to the formation of necrotic or dead spots on the leaves. This is because calcium is a crucial part of the plant cell walls and a lack of calcium weakens the plant's overall structure. Long-term calcium deficiency can devastate your plants and lead them to die off.
