Hello,

My cucumber plants don't look so good. The only thing I have ever applied to them was a solution of water and baking soda (1 gal to 1 tbsp) to control powdery mildew that had started forming. The solution caused the spots where the PM had formed to die and turn brown, but it was only a few spots on the lower leaves and it seemed to work. About a week ago I noticed the PM coming back so I sprayed again, and now they're looking like this.. any ideas?? Do I need to pull them? Any help would be greatly appreciated! Thank you.
