What are two signs of nutrient deficiency in plants?

Wilting and loss of leaves can indeed occur due to various stress factors, including environmental stress and water issues, but they are not direct indicators of nutrient deficiencies. Stunted growth and discoloration of leaves, however, are classic signs of nutrient deficiencies. Specifically, when a plant lacks essential nutrients such as nitrogen, phosphorus, or potassium, it can exhibit stunted growth due to inadequate building blocks for cellular processes and energy transfer. Discoloration, such as yellowing leaves (chlorosis) or purpling (often due to phosphorus deficiency), further indicates that the plant is not receiving the nutrients it requires for proper development. This response encompasses essential physiological responses that help identify nutritional problems in plants, making the choice highlighting stunted growth and discoloration the most relevant to nutrient deficiencies.
