Symptoms of the disease can be mistaken by nutritional problems since they manifest as a yellowing or browning of leaves. However, if the abaxial side of the leaf is inspected, profuse, dark sporulation will be covering the surface of infected leaves. Usually, the sporulation is obvious enough that it can be seen without a microscope or hand lens, however, when you take a closer look at the sporulation on the leaf with a hand lens or dissecting microscope, you will be able to see the typical sporangiophore structures bearing sporangia found in downy mildew pathogens
