Texas Gardening: What is wrong with my Lavender..Help Please, 0 by quickerhorses

Hi. First time for me planting Lavender. I planted about 50 this spring. I live around the Stephenville, Texas area, where it has been extremely hot, 105 most everyday, no rain at all. Everyone told me not to over water, so I have listened, or so I think. I water them about once a week or so. I have noticed that some of the plants looks like they have been freeze dried. They are not yellow, like if you over water, not brown or wilted like under watering. They just simply look like I have freeze dried them. It starts with one clump on the plant, then slowly spreads to other clumps, until the whole plant looks like that. Does anyone know what is going on?
I have checked the soil, doesn't seem to be too dry or too wet, I have sprinkled some Seven dust on the plants that have started this process just in case they are being attacked from down under. We have a million grasshoppers this year, but to me it doesn't look like any plants have been chewed on. I sure would appreciate any clues, before I lose all of them.

Thanks!
