Likely causes
Mineral buildup
Most likelyHow to tell: The tips turn brown and crisp while the rest of the plant looks healthy. This often happens if you use hard tap water over a long period.
What to do: Flush the soil thoroughly with distilled or filtered water to wash away excess salts. Switch to using rainwater or filtered water for your future watering sessions.
Underwatering
PossibleHow to tell: The entire plant may look slightly shriveled and the tips turn brown from dehydration. The soil will feel bone dry and pull away from the edges of the pot.
What to do: Soak the pot in a basin of water for 15 minutes to ensure the root ball is fully saturated. Resume your normal schedule of watering every 7 to 14 days once the soil is completely dry.

When to worry
Worry if the browning spreads rapidly to the stems or if the plant begins to collapse. Minor tip browning is often just a reaction to environmental changes.
Stopping it coming back
Use filtered water and ensure the soil dries out completely between waterings to keep the root system healthy.
