Sticky Leaves on Plants
Lower leaves of all my plants in three rooms are very sticky/shiny. Dirt has patches of grey matter. What can I do?

This is honeydew and the result of a pest--likely aphids, scale, mealybug, or similar sap-sucking insect. Treat the plant and soil with neem oil as this should take care of the pest and any fungal issues that may result from the honeydew.
