Funky Watermelon Leaves. Can I save the plant or watermelons?
All of the sudden my watermelon plant leaves (mainly the bottom/oldest 35%) have been turning yellow with brown spots. Some also have white (non-powdery) funk going on like in the photo.
I have 4 sugar baby watermelons that I am waiting to ripen and hopefully save. I don't know if I can save them though or the plant.
Does this look like a fungal infection? Should I buy a fungicide?
