I won't pretend to be an expert, but I'll give my own obserrvation. Mine gets reddish-brown spots on the leaves as a response to direct sun. If the texture & overall look of your plant's leaves seem healthy, that may be the case with yours, too. That extra sunshine might make the leaves look less than perfect, but it does bring on the blooms!

Thanks, Ooojen. I hope that's all it is. By the way, is there a way to post pictures in this forum? I had thought I did, but evidently not. Do people use the Cacti Gallery?

You can put pictures directly in your thread from a picture hosting site, but if you want to skip a step, there's a Hoya Gallery, too.

I don't use a picture hosting site, so I just posted a picture of the leaves for you on the Hoya Gallery. Thanks for calling it to my attention, Ooojen.

Thanks. I'll try that. The brown spots just remind me of apple rot so much that I panic.

I also get small brown spots on my K8/C due to direct sun as well...I notice it on the top/upper leaves which are more yellow. They get more sun and are of course older leaves as well.

Thank you all. To tell the truth, though I am sorry for harming the plant, I am relieved to know that it is sunburn and not some horrible disease that will kill the plant. It is hanging from east-facing eaves, a foot or two from the white stucco wall of the house, and only gets morning sun. Of course, it gets more sun in this season than in others. The long shoots it puts out have nowhere to go, so they hang down. Would it do better if I let it climb up a tree (not that I have many candidates for that job, either)? Will it climb up a tree? I appreciate all the comments.
