Answer 1

Is that a variegated lemon tree or are there light and dark areas on the foliage? From the photo, you may have downy mildew going on. I will also include powdery mildew information, but you will be able to tell after reading the descriptions.

I can't get a real clear look at the photo, but also check for spider webbing or evidence of mealy bugs or scale.
