Why do plan leaves go brown on the edges?

Plant leaves can turn brown on the edges due to several factors, including insufficient water, nutrient deficiencies, or environmental stressors like extreme temperatures. When plants are under-watered, they may not be able to transport enough moisture to all parts of the leaf, leading to browning. Additionally, a lack of essential nutrients such as potassium can cause leaf edge burn. Lastly, exposure to harsh conditions, like strong winds or direct sunlight, can also contribute to this issue.
