What are the signs of calcium deficiency in a plant?

Calcium deficiency in plants is often characterized by specific symptoms that can help identify the issue. Light green leaves with upward leaf margins are a clear indicator of this nutrient deficiency. Calcium is crucial for cell wall structure and plant growth, and when it is lacking, the leaves may not develop properly. This results in a lighter coloration, often described as light green, and the upward curling or cupping of leaf margins is a common visual symptom.

In contrast, dark green leaves typically indicate an abundance of nitrogen or healthy foliage. Wilting leaves could suggest water stress rather than a deficiency, and yellowing at the bottom of a plant is often associated with nutrient deficiencies like nitrogen or can be a sign of overwatering rather than a calcium issue specifically. Understanding these symptoms is essential for effective plant care and nutrient management.
