Based on your description, it almost sounds like late blight. Try searching online for late blight photos to see if this is it. How long has this particular plant been doing this?

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.
