Chili pepper problem

Question

I am growing chili pepper plants and a tomato plant on my lanai. I discovered both of the pepper plants were covered with a white powdery substance on the underside of their leaves and have tiny white “flies” buzzing around the plant, as does my tomato. Is this powdery mildew or white flies or both? My tomato fruit has a hole in the underside also. Any idea what is causing this? I live in either zone 9 or 10. My zip code is 34952, South Florida.
Thank you!

Sometimes a stressed plant just begins to invite more than one issue.

Excess heat or damp conditions can be a source of the issues.
Neem Oil is a good way to treat the insects and fungus.
