Mold on tomato plant leaves?

[Teagan]

I have never seen this before on my plants. On the lower leaves, there looks like what is fuzzy mold on the top of leaves. On another plant, I noticed a dot of What looks like mold On the top of a few leaves. We have had a heat wave in Chicago but no rain. Has anyone else experienced this? My flowers are dropping like crazy on my dwarf tomato plants but I blame the excessive temps. I’m at a loss btwn the mold and blossom drop. My basil is doing great lol Any suggestions would be greatly appreciated.  Thank you.
*I’ll try to upload a photo later. I removed most of the leaves with mold but saw one that I missed this morning.

If it's been hot that can take a toll on the tomato flowers. I'd like to "see" the mold. resize your images to 288 pixels x 288 pixels and you should be good
