Nitrogen deficiency symptoms typically appear first on the older or lower leaves of a plant. This is because nitrogen is a mobile nutrient, meaning that the plant can translocate it from older tissues to younger ones when there is a shortage. As a result, the older leaves show signs of nitrogen deficiency, such as yellowing (chlorosis), while the younger leaves remain relatively unaffected initially.
