I have a nobile-type den I grow outside, and a few of its leaves have a ding or two. Yours looks okay from the pictures, and if all goes well, both of ours should be losing all their leaves within the next month.
Have you treated it with basic insecticidal soap (1 part rubbing alcohol, 3 parts water, tablespoon or so of dishwashing soap)? If not, try washing top and bottom of the leaves with that, and soak the pot in it for 1/2 hour or so (then flush out with plain water) in case there's bugs in the pot. If there are no bugs - won't hurt anything; if there are, should zap 'em.
My experience with mine is that it can take full sun - and it's been over 100 this summer - without harm as long as it gets lots of water while it's growing. It's about time for it to enter its winter rest period, so it's starting to get less water and natually less sun due to the rotation of the earth the tilt of the axis and all that!
Hang around ... someone will come by and give you more better advice! I'm glad to see your keikis made it! They look terrific!
