Any idea what's going on with this? There's nothing on the back of the leaves--no bugs or anything. And so far it's just the lower leaves. It's also only my younger blue flames (maybe 8-10" across) that are affected. My big one seems to be doing fine...
I several agaves, three of which are the gorgeous hybrid known as "blue flame." Two of my three blue flames, though, have recently become plagued with a few little brown spots on their lower leaves.

Even though you don't see the bugs now that doesn't mean they weren't there or come in the night. I think since it's lower leaves (near ground) it is a bug sucking some juice out. You can add a systemic bug killer with fertilizer to the soil. Sometimes I do this. It's usually for roses but works really good. Just an idea.
I have a tends ct to start with the simplest remedy for a certain problem, maybe it's from attending law school or watching too much Big Bang Therory but I'm a firm believer in Occam's Razor - It states that among competing hypotheses, the hypothesis with the fewest assumptions should be selected.
