Spray or chemical damage
Cleaning products, pesticides, foliar feeds, or other sprays can injure leaves when mixed incorrectly or used in unsuitable light or temperatures.
WatchPossible cause—not a diagnosis. Compare the visible signs, plant identity, and growing conditions before treating.
Signs you may notice
- spotted burn
- bleached droplets
- damaged new growth
- sudden injury
Safe first checks
- Review every product used in the previous several days and compare the damage with droplet patterns and the most exposed leaves.
- Photograph the affected area in clear natural light.
- Review recent changes in light, temperature, water, feeding, or location.
- 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.
- sunburn
- bacterial leaf spot
- broad mites
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.
