Nitrogen deficiency
mediumOlder, lower leaves turning uniformly pale yellow while new growth stays green is a textbook nutrient deficiency.
Favorable conditions
- •Plant hasn't been fertilized in several months
- •Recent repot into nutrient-poor soil
- •Heavy watering has leached nutrients out of the soil
Management
- 1Feed with a balanced liquid fertilizer at half strength.
- 2Resume a regular feeding schedule every 2-4 weeks during the growing season.
- 3Trim off severely yellowed leaves — they won't turn green again.
- 4Watch new growth over the next few weeks for improvement.
