Default Gray mold, GRSV, other?

We've had record setting rainfall in the month of May and I really only remember 2 days in May with sunshine, the rest raining or at least overcast. It is pouring again as I write. Earlier this week I spotted gray mold on a few plants and used bleach spray to try to control it. I have already done that once and have used neem, daconil, and a combination of Copper and Mancozeb previously.

Since spraying bleach the second time, I've had lots of leaves still dying. Others yellowing with ugly patches of dark colors on them and even some stems that have a gray/brown look to them. The stems have me officially concerned. I keep removing the affected leaves and have removed a lot of affected leaves. I'm unsure whether to double down and hit them with bleach again or if I burned them somehow, though I carefully measured the 5 ounce per gallon amount an mixed it by shaking the entire time I sprayed. I believe it was just that I had much more mold that I knew, but, now I'm not sure.

I've been battling thrips this spring and they are winning! I know what they can do (infect plants with TSVW) so I've been employing numerous means to try to control them.

In looking at images for leaves that look like mine by searching TSVW, I found this page. http://entomology.ifas.ufl.edu/pesta...t_ringspot.htm

My leaves look somewhat like these images and some of the stems look like those in figure D. I also see that thrips are a vector for this condition GRSV and am wondering if this is going on.

After all that, here as some pics, awful pics. Your input appreciated!
