Weird black spots vol. 2 - this time on my Bl. Morning Glory!

I've attached a photo of the above-mentioned spots. Are they just aging signs, or could it be pests or fungi? I don't see any visible pests on the orchid, and I think it might have been like this when I got it. The spots are only on that one leaf and on the tip of another leaf, but the rest are green and healthy.

That could be from pests, tho, could be from a while back, especially if you don't see any pests, and the marks are only on old foliage. If it were mine, I'd keep an eye on things, but not worry at this time.

Thanks, Sonya!
