On one of my plants, brown, drying decaying leaf material that progresses from the margins inward, eventually killing the leaf. I have this on the margins of several leaves. Pictures on my diary page (SoCal Kevin). Downy mildew or maybe potassium deficiency? What should I spray!?

On the other plant, there are yellow spots in the center of a few leaves, as well as on the fringes.

Thanks!

Just my 2 cents. Brown appears chemical/fertilizer burn. I've noticed that yellow blotching and edge yellowing in several plants that have 1495 in their ancestry. Typically no problem.

See pic below, this took a while to develop on an isolated section of the plant. This was from spray burn when the leaves were too little to take the hit. I eased up, and the rest of the plant grew out perfect. Not saying that is what you have, but to corroborate what Dave said.

Home of happy lil plants

sprayyyy dmg all around ive done my fair share of that... spray less in the heat and avoid spraying leaves smaller than 6in in or so is best i can do to avoid it(while forming)

That looks just like all my plants this year I went a little heavy on the spray. It was a couple weeks ago and now looks like someone took a blowtorch to my plants......

Don't ya just hate that! :(

In a couple weeks it will be like it never happen,,,,,,,, then I'll do it again. lol
