How can over-fertilization of a plant be identified?

Over-fertilization of a plant can be identified by symptoms such as leaf burn, excessive leaf growth with few flowers, and stunted root development. When a plant receives too much fertilizer, particularly nitrogen, it can lead to rapid, lush growth of leaves at the expense of flowers and roots. The leaves may exhibit burn or scorch marks due to salt buildup, which can cause dehydration and tissue damage. Additionally, while the foliage may appear vigorous initially, the overall health of the plant is compromised, leading to weakened roots that cannot adequately support the plant. This condition ultimately limits the plant's ability to produce flowers and fruit, as its energy is diverted towards managing the excess nutrient load instead of normal growth processes.
