Help diagnose. Dont see any pests.

Check leaf septoria

Looks kind of similar to septoria, how's the humidity and rain been lately Jim?
(the white residue is baking soda spray not pm)

Well the rain has been torrential and the humidity unbearable. It's not really yellow, rather white and the white spots are brittle. I thought it looked like septoria myself but comparing to other pictures it kinda dont. They're still in veg so I'm gonna hit with some daconil. If you look closely at the leafs the bottom right corner on the first pic, you can see a bunch of little holes, like a pest, but I'm not sure. I emailed GardenTech to see if I can mix daconil and malthion for a fungicide-pesticide combo but they have not replied.

Could be two things going on? ..would treat with a liquid copper fungicide if it continues to get worse

Well I already did the daconil this morning before I got your copper post idea. Do u think if I let the spray dry and came back this evening when sun is low, I could spray insecticide on top of fungicide? Daconil says on bottle is for septoria. I'm just not wanting to wash daconil off with pesticide spray. That's why I was wanting to combine the 2 but GardenTech never answered. I really appreciate your input.

It's funny though. I have 5 plots in 5 different places in a half mile square area and only one plot is showing symptoms but all 6 plants in that area are doing so. My other 25 plants are not showing symptoms.

i's wait a couple of days, if the dac works, no need for anything else, if it doesn't i'd try the copper fungicide.

could be that one patch is infected, i'd be going to that one last if i was you, so as not to carry anything from that spot to the others

NO! Please wait several days! I would do what Rodger said above for best results

Regarding liquid copper fungicide someone in my general area uses it extensively on his outdoor crops and he recommended highly. I've never used it even though I bought it recently, I burn sulfur and that has stopped everything

Thanks, I wait and see what happens.
