Seems like it would be early to make that judgment based on the pictures. Different types of blemishes will often appear for whatever reason and not recur. The leaves show some irregular margins, which isn't at all uncommon with going through a little stress from transplant or plant-out adjustments. Something like that could factor in.Â

The other thing I note is the leaves have the appearance of a sheen or residue on them. Could just be the pictures, but have you treated the leaves with anything?
