I have been watching the bottom leaves on my Lemon Cukes slowly turn yellow and die over the past month or so- concerning though great for improved air flow at the bottom of the plants.  The top of the plant is doing great and doesn't seem affected (although these cucumbers were super slow to grow).  Caveat, I have no cucumbers yet but I think that is because I have had 98% male flowers so far.

I think it is powdery mildew.  I will attach a picture to see if you agree or not- but it  seemed a little better after one application of Neem oil 3 days ago.

I started tonight to do a 50/50 mix of (1%) milk and water and apply every 2-3 days.  Not really a double-blind randomized controlled trial- but I have limited space and cuke plants and I couldn't get IRB approval.  I'll keep you posted.
