Low Light
Possible

When to worry

If the stems are so thin they cannot support the weight of the leaves, the plant is in danger of snapping. It is normal for the plant to have some space between leaves as it grows taller.

Stopping it coming back

Ensure the plant receives consistent bright light and avoid overfeeding with nitrogen rich fertilizers.
