What Does Light Burn Mean?
Light burn can be seen if the plant has yellow leaves. If the leaves point up, this can be a sign that they are getting too much light. It's important to keep in mind that even with light burn, the inside veins can remain green and the leaves don’t fall off easily. This is fairly common with indoor plants.
Plants can only withstand a certain amount of light. The lights that are closest to the light source may show signs of burning. Light burn may also be visible on older leaves that have been exposed longer. Heat stress and light burn typically occur at the same time in plants.
