Do pale leaves mean a plant needs fertiliser?
Not necessarily. Light, root-zone conditions, and pests can overlap with colour changes. Check these factors before adding fertiliser.
Can insufficient light make foliage pale?
Yes, low light can be associated with pale foliage and stretched growth. Compare the plant's current exposure with its own light guidance before making a gradual adjustment.
Should I move a pale plant directly into full sun?
No. A sudden move into intense direct light can damage foliage. Make gradual changes that suit the specific plant's light tolerance.
