Tomatoes have Septoria and Blight, need organic help?

I really do not want to use fungicides in my garden to control my leaf disease that is the very last option, so please just let me know if you have any proven organic, natural, or home remedies to help me.
I noticed it this morning and it is my fault. I usually hand water my garden but with the heat and humidity I started just turning on the sprinkler and going back inside. I didn’t realize just a few days of this could do so much damage. I’ve also slacked a little on the upkeep and stuff.
I have cut back most of the damaged leaves on the tomatoes, and pulled a few plants out to help with air circulation. I have also pulled out my basil because it looks like it was affected as well. I did leave a few leaves on there because the plant is in direct sunlight for 10-12 hours a day and I do not want it to be scorched.
My mother suggested I mix some soap, water, and vinegar and spray the leaves, any one heard of this? Not that I don’t trust her but before I start spraying away I want to here what has worked for others in the past.
What organic, natural, or home remedies does anyone have to control my Septoria and Blight?
