Yeah, I see some leafminers. Not a problem unless there are a lot. Imidacloprid or Spinosad will control them. App timing is critical - spring. Worst pests are mites, scale and mealybugs.
I see no greening going on. I do see some nutrition issues. Peters 25-5-15 or Dyna-Gro Foliage Pro will take care of it.
Keyplex 350DP is an excellent source of micros, a quick green up if applied foliar. Make sure and add a surfactant to your spray or you're wasting your time and money.
