I don't know if that's the problem but that's way too much fertilizer

hhhmmm,thats strange,i have been doin it that way for years and never had a problem.
oh and b.t.w.
my tomatoes have it too.

I'm not sure but that does not look like too much fertilizer. It looks more like the weather's too hot or not enough water.

you are correct azzz.i never opened the valves on my drip station,so they were not getting any water.oops!
