I have about 10 cucumber plants in my raised bed (12ft x 4 ft) and the image attached shows some yellowing of some of the leaves. These plants were mowed through by deer one night (ughhh!) and what you see are what remains. Is this a fungus from too much water or possibly a pest that i need to eradicate? Doing this the organic way so I'm staying away from non-organic pesticides.
thanks in advance!
