Built a partial hoop house over the tomatoes on the advice of a local commercial grower. The plants still get wet from blowing rain and dew however.

Am I correct to think this is either early blight or some form of mold/mildew? I've sprayed bleach after rains, daconil once, then recently, Mancozeb and Copper Fungicide.

Thanks,
Mike
