The leaves look okay to me, in fact very healthy except for the few with scorch spots. Its not unusual, and nothing to worry about. And your new garden is amazing!

Mb, could it be some type of frost? Toni

Looks like it could have been sunburned where water was left standing on leaves.

The black spots which are turning gray is sunburn from last year.

If you don't like to look at the few affected leaves, remove them. Otherwise, leave them be.
