Too much light can cause problems such as sunburn, leaf scorch, wilting, and yellowing. Some indicators to look out for are:
Leaves becoming pale, bleached, or faded in color.
The edges or tips of the leaves turning brown, dry, or crispy.
The leaves are curled, droopy, or wilted.
The leaves are developing white or brown spots or patches, which indicate sunburn.
The plant is growing leggy, spindly, or stretched out, which means it is reaching for less intense light.
You can relocate or just use curtains, blinds, or sheer fabrics to filter the light where it shines over them. You should also check the soil moisture and water the plant as needed, since too much light can increase water loss.
