Need help with pest control, black dots all over...
I noticed some strange things happening to my plants and it seems widespread. I already let go of my Bella plant because of some pest, spider mites IIRC, but it seems that another pest is attacking all my plants at the same time.
I uploaded some high resolution pictures and added the link so you could see them and kindly give me some advice whether these are some sort of pests and I should handle them or it is something entirely different.
When I touch under the leaves, the dots seems to be internal and not external, so I cannot remove them by washing the plants.
Here is a link that might be useful: High Resolution pictures of some infected plants
