Advice for house plant pests
I have an indoor Hibiscus plant, it had minute brown dots on the leaves that cane off if I rubbed them off, that looked like they were sucking the juices out of the leaves, I soaked it under water as advised for 1 hour and these things went away. Now the leaves are growing back but they have clear spots on them like something is sucking the leaves again, I can’t see any insects or minute bugs etc, has anyone got any ideas what is causing this and what I can do to get rid of the problem, should I soak it again? A photo of the leaves will follow. Thank you.
