Sonya,

Crispy leaves, and I assume by 'crispy' you mean that they are both brown and crunchy, are dead leaves. Just telling us that you have dead leaves doesn't give us enough info to allow us to offer any sort of diagnosis. We need to know what they looked like before they turned crispy. Even then, it can be hard to diagnose anything based on a verbal description.

With both the okra and the tomato plants, what did the leaves look like before you noticed they were crispy? Had they been a vibrant, healthy green and then turned yellow or yellowish-green? If they turned yellow or yellowish-green, was it a solid color or a mottled color? Were their any brown, black or purple spots or splotches? Were there brown to brownish-black bull's eye type concentric rings with varying colors? Any wilting? Any spotting or discoloration on the fruit? Have you checked the backs of the leaves for spider mites? I can think of lots of possible reasons for the tomato foliage turning crispy--some deadly and some not with treatment, but cannot think of many options with the okra other than spider mites, nematodes if you have sandy soil, or cotton root rot.

I'm going to link the TAMU Tomato Problem Solver Website. You might try looking at the leaf diseases there and see if anything resembles what you're seeing on your plants.
