Yellowing orchid leaves may be caused by the following factors:

3. Soil issues: Soil that is too acidic or alkaline can affect the growth of orchids.

4. Pests and diseases: Such as powdery mildew and anthracnose can also cause orchid leaves to turn yellow.

3. Soil Issues

- Acidic soil: You can apply lime in moderation to adjust the soil's pH.

- Alkaline soil: You can apply ferrous sulfate in moderation to adjust the soil's pH.
