Brown leaf tips are worrying, and they are also hard to read. The same brown tip can come from more than one cause, so tips alone do not give a certain diagnosis. The useful move is to review the likely causes together, then change one habit at a time so the real cause has a chance to show up.
Possible cause: inconsistent watering
Soil that swings between very dry and very wet stresses leaf edges. Check the soil before watering, water thoroughly, and let excess drain, so the plant gets a steadier routine rather than feast and famine.
Possible cause: dry air
Dry indoor air can dry out leaf tips, especially in heated rooms. If the air in your home runs dry, moving the plant away from heat sources and grouping plants together can help the air around the leaves stay a little less dry.
Possible cause: feeding
Feeding is one factor worth reviewing. Too much food, or food given to a plant that was not actively growing, can show up as brown tips. Review how often you feed and whether the plant was growing when you fed it. Bloom Nutrients A+B plant food at $16.99 is one feeding factor to review in that check. It is not a cure for brown tips, and adding more food to a plant with brown tips can make things worse.
What to do now
Trim only the dead tip tissue, cutting back to healthy leaf so the plant looks tidier while you work out the cause. Then change one habit at a time: steady the watering, adjust the spot, or review feeding, and give the plant time to respond before changing something else. New growth that comes in healthy is the sign that you found the right change.
Brown tips are a prompt to look closer, not a verdict on your plant care. Wherever you call home, a steadier routine is usually the answer.
