I'm going to have to see plants (send these overnight mail to me). I am concerned this might be impatiens downy mildew, but the only way I can confirm is to see plants. Just to be safe and until I can confirm (or not), see the links below for details on the disease. Control involves a combination of eradicating diseased plants and fungicide treatments.
