Leaves that are a shade of very dark green can be a sign of nitrogen toxicity.
=== "burned" leaf apex ===
The fan leaves will also show signs of any nutrient burn taking place. Nutrient burn symptoms occur at the tip of fan leaf "fingers" (the apex) where the leaf turns brown and crispy
=== Claw fan leaves ===
The apex of the leaf clawing down can be a sign of wind burn (airflow being too intense) or nitrogen toxicity
