Fertilizer or salt burn

Excess soluble salts can injure roots and leaf margins.

WatchPossible cause—not a diagnosis. Compare the visible signs, plant identity, and growing conditions before treating.

Signs you may notice

  • brown tips
  • scorched margins
  • white crust
  • root damage

Safe first checks

  1. Review product strength, application date, water quality, and visible crust on the pot or medium.
  2. Photograph the affected area in clear natural light.
  3. Review recent changes in light, temperature, water, feeding, or location.
  4. Change one likely cause at a time and record the result.

Can look similar to

Overlapping symptoms are common. Compare these alternatives before choosing a treatment.

  • low humidity
  • underwatering
  • sunburn

What to avoid

Do not make several care changes at once; that makes the response harder to interpret.

Record and follow up

Photograph the same area again and record one change at a time. Compare new growth and whether the symptom spreads, stabilizes, or improves.

Seek qualified local help when damage is severe, rapidly spreading, or may involve a regulated pest or disease.
