"It only affects us here when the weather is hot and humid -"
What day and year was that?
So we had light rain all night. Damp and intermittent rain all day. I went ahead and hit two plant full
soak. Found one spot on a 4inch pot, potato leaf plant. Soaked the leaf. Rain has stopped and plants
are dry-ish. No signs today. No leaf death on soaked plants. (most are under the eaves hardening
off).
So far so good. If I see a return I may up the potassium Bicarbonate amount in the mix....
baby steps.
