Wilting and Yellow/Brown leaves
Hi, I'm new to gardening. have a small plot in our community garden in central FL and I've planted a number of vegetables from seeds and some transplants. A lot of my plants have leaves that sort of look like they are wilting -- especially the Okra (see picture). At first I thought it was red ants because I've seen a lot of those in the garden. I've also noticed a lot of tiny yellow ovalish things on the underside of leaves. A lot of plants have yellow and brown spots (especially the pole beans) and are losing leaves. My cherry tomato plants and sweet potato have also been affected. It seems that the leaves on the bottom of the plants have more damage than the top (for the tomatoes).
Any idea what is causing this? What do I do? Thanks in advance for your input :)
