Common Causes of White Specks on Plant Leaves

-
Mealybugs

Spider Mites

-
Scale Insects

Additional Considerations
Environmental Factors
Environmental stressors such as low humidity, extreme temperature fluctuations, or poor air circulation can exacerbate pest infestations and fungal diseases. Regularly check your plant’s environment to ensure it meets their specific needs.
Regular Maintenance
Preventative care is vital in keeping plants healthy. Here are some practical maintenance tips:
