We put in the second crop a few weeks ago. The okra and pink eye peas came up like gangbusters. I've used only good soil prepped with black cow, harmony organic fertilizer, azimite and compost. A few of the leaves on the okra and peas have white spots on them. The plants all look really healthy and strong. The spots don't flake or powder. They're just white spots on the leaves. They are only on a few plants. Do I have a problem?
