Zucchini Problems? Maybe Not: Small Soft Yellow Fruits and Not So Powdery Mildew

I had no problems at all last year with zucchini, until the end of the summer that is. But even then, I was harvesting large zucchinis.

This year, it appears I will have some good zucchinis with my one plant (vs. my 3 last year), but I'm also seeing some soft, yellow fruits that aren't quite developing. See below:

This might only indicate that pollination isn't happening on these particular fruits. I've taken to just cutting those fruits off, and monitoring the rest of the plant, which is actually producing some healthy looking zucchini plants.

And what I thought was powdery mildew has made an early appearance this year. Or is that what it really was?
