Overwatering or a nutrient gap
Widespread yellowing usually traces back to soggy roots, or a long stretch with no feeding.
Diagnosis
Overwatering or a nutrient gap
What's happening
Yellowing across many leaves at once is most often advanced overwatering (check the roots first), and occasionally a plant that hasn't been fed in many months.
How to fix it
Check the soil and roots: if wet or rotting, treat as overwatering — dry out, trim rot, repot. If the roots are healthy and it simply hasn't been fed, resume a balanced fertilizer at half strength every few weeks in spring and summer.
What fixes it
- A balanced liquid fertilizer — A balanced liquid feed at half strength restores color over a few weeks.
If that doesn't fix it
This is general guidance based on common symptoms; individual plants vary.
