Leaf discoloration: Could this be from bugs?

[Reeses]

I noticed some discoloration on my NOID onc. when watering today. I hadn't noticed it before. It looks almost like the leaves have dehydrated on the discolored areas. I am a bit concerned, because I wound up having to get rid of a seedling zygo a few weeks ago due to some sort of small bug in the media. They were buried way in there, and I didn't see any wings, but I suppose it's possible they hitchhiked somehow?

Also, I don't know if it matters, but I suspect it is a Tsiku Marguerite, based on the blooms. Or at least something very similar to that. It is potted in a clay pot with sphagnum broken up by LECA.

What do you all think? Bugs? Or something else?
