Last one.... thanks again

a pic of the yellow spots

seysonn's response has image of early blight. OP's image is *not* early blight. Here's info from NCSU (see link) And here's a portion of NCSU info: "Infections of early blight usually begin when water splashes infected soil onto lower leaves or the stem. (The disease can also come on the plants from the garden center.) Soon afterwards, black spots develop that may be surrounded by a yellow area. The spots grow in size and number, spreading upwards towards the top of the plant. As the spots grow, they form a bulls-eye pattern. Lower leaves eventually wilt and fall off." Hmmm. Doesn't sound like OP's plants or symptoms. Here is a link that might be useful: early blight.

One of the things I'm doing this year is interplanting basil with melons and squash. The melon and squash vines just grow all around the basil, which grows well above them, but the roots don't really share any soil. So while the basil produces just a smidgen of shade on the vines below, it's otherwise wholly independent. I can load up N fertilizer on the basil without overloading the melons and squash. This is in a bed that gets 100% sun, so a bit of shade is no bother. I never bother planting new basil. I just continually harvest from individual plants, and they just keep churning out more. But I'd better stop talking about basil in a tomato thread.
