They look a bit sunburnt to me. I wouldn’t consider it a goner, but in the future might start hardening off sooner. New leaves should grow in better shape.

i would have put them in deep shade outside for a week ... then bright shade for a week .... then a week of morning or evening sun ...

and i would have started about .. wait for it.. 3 weeks ago ... lol

look to the growth tips.. the new leaves will immediately be sunproof ...

i wouldnt be too concerned if you eventually lose these few leaves ... and look close.. they are 90% fine.. still doing their job ...

My thot is leafminers. Backlight the leaf with the sun. The critter may still be feeding between the layers of the leaf.
