Hi ofm, they do appear to be dehydrated. How often are they getting water?
What type of soil are they growing in?
With the weather we have been having lately in the Willamette Valley, I would water them maybe once a week, in the evening.
Mine started to look like that because I hadn't been water. Once I started watering they quickly improved in color and health.
Just don't water in the heat of the day. That will steam cook them.
