Spots- I see them now and don't recognize them. Preventative misting with SMC leaf wash is never a bad idea. It forms a protective barrier against insects and pathogens. Neem oil does too, but you need to be very reserved in your spraying it; mist lightly, allow to dry, repeat as necessary to maintain shine.
