This year is very different time wise (early) for disease. None of the fruit is showing spots or deformities.

I have never seen that reaction to the bleach solution. Did you spray when the sun could hit the wet leaves? I don't know what a 5% solution means because of the differences in the formulations of different brands of bleach. I now use only the Clorox with the 8.25 % sodium hypochlorite and add 5 to 5.5 oz to a full gallon of water along with a few drops of dish washing soap.
You need to follow up the bleach treatment with a copper spray and remove as much of the diseased foliage as possible. Septoria is very hard to control and you may have to treat it multiple times to get it under control. By spraying only the bottom two feet of the plant you have done nothing for any disease above that area so watch out for it spreading.
