Although nute burn is normally a more tan color.... If the problem only arose after the feeding of nutes, then most likely its simple nute burn. IDK if you really needed a flush just cut back on your next feeding. Go to a 1/4 of recommended feeding, then up to 1/2 if the plant continues to respond well then try for full after that. Just do it is phases and steps that way you can get a better idea of what your plant truly wants. Also she looks a bit small with some good soil, idk if feeding is really needed expecially not 100% nutes.

Looks kind of like water droplets that got on the leaf and light burned thru the droplets.
Do you foliar spray?

I wouldn't worry about it.

You are a new mom worrying because the baby sneezed.
She's ok mom. Keep doing the right thing and she'll grow up big and strong.
