Four clues before you change care
Look first. Change one thing. Judge progress by new growth.
Pause for wet or fast-spreading damage
If tissue is wet, mushy, or spreading quickly, move the plant away from other plants, keep leaves dry, pause fertilizer, and avoid sharing pruning tools. If damage continues to spread, ask a local horticulture professional to inspect it.
-
What does the damage look like?
Mark one: crispy tips or edges · separate dry spots · wet, mushy, or spreading quickly
-
How wet is the potting mix?
Mark one: dry deeper than usual · slightly moist or unclear · wet for several days
-
Do you see residue or recent feeding?
Look for white crust on the mix or pot. Note whether fertilizer was added recently.
-
What surrounds the plant?
Note heaters, vents, very dry moving air, and strong direct sun on the affected leaves.
Match the pattern to one cautious next step
These observations narrow a starting point. They do not prove the cause.
Wet, mushy, or spreading quickly
Use the isolation steps above. Do not apply a broad treatment while the cause is unclear.
Wet for several days
Hold the next watering. Empty standing water and check that the drainage hole is open.
Separate dry spots and strong direct sun
Move the plant out of harsh direct sun but keep it in suitable bright light. Watch for new spots.
Crispy tips and white residue
Pause fertilizer. At the next normal watering, use low-mineral water only if the pot drains freely.
Crispy tips with dry mix or dry moving air
Water only if the mix is dry to the depth that suits this plant. Move it away from hot or cold drafts.
When the pattern is still unclear
Keep care stable. Photograph the plant, both sides of one affected leaf, and the mix. Add the date and recheck in several days.

Brown tissue will not turn green again. Look for whether damage spreads and whether new growth develops without the same pattern.
