White mold on cucumbers

Hi all just noticed white mold on cucumber leaves the be sprayed it with the milk water mix anything else l can do thanks all

 

Nope.
Atleast I dont think so, other than keeping up with the watering and humidity.

 

I've the same problem would keeping the green house moist and spraying around the leaves or will cause more damage

 

I still say the same, keep the roots moist and humidity up.
A milk solution may well help, sprayed on the leaves.
