Common Symptoms
Leggy growth
The whole plant has unusually long, weak stems, pale foliage, and widely spaced leaves.
Signs to check
- The space between two leaves, or internode, is noticeably longer than on older parts of the plant.
- New leaves are smaller and paler green, or even yellow, compared with mature leaves.
- Growth is strongly directed toward one side.
- Stems are thinner and more flexible than normal and struggle to support the weight of leaves.
Common causes
- Low light · The plant stretches, turns pale, and leans toward the window.
- Nitrogen deficiency · Older leaves turn uniformly yellow first.
- Water stress · The plant droops and its leaves turn yellow or brown.
