You very well could be having issues related to translocation of your neighbor's herbicide application. I've seen this happen, most recently in my own yard when my Super Dw. Cavendish had some leaf deformation problems and even some splotches that looked variegated after I applied glyphosate (Round Up) nearby. The plant grew out of it in a few weeks and is doing great now.
I see that you realized that your fertilizer did not contain micronutrients and got one that did. This is always an important thing to pay attention to as many fertilizers only have N-P-K and no micros. Micronutrients, as the name implies, are needed in very small amounts but they sure do make a huge difference when they are lacking, as you may be seeing in you plant's leaves. You might consider getting a soil test done through your local Cooperative Extension Service as applying fertilizer when it isn't needed is just as bad, or worse, than not fertilizing at all.
