I hate to say it but I think you have Septoria Leaf Spot in all 4 pictures. On the first two pictures I see 2 or 3 leaves affected. The yellow leaves could be from early blight but I don't think so as I can also see septoria.

Just google septoria leaf spot. There are a lot of sites addressing it.

Thanks so much Chuck! Going to proceed as such... wasnt sure about the last 2 pics, as its just crazy wilt/yellowing on 1 side/couple of branches. No black spots. Much appreciate the quick reply!

Cut back all diseased foliage/stems and 1st application of 'Serenade'... will let y'all know the outcome.
Lots of fruit is set, and still lots of healthy foliage, so hopefully got it nipped in the bud....
