Anyone ever have an issue with white powdery mildew on their plants?? I am noticing it on some of the lettuce, mostly the red variety. I'm planning to spray with milk/water (1:4 ratio) as I read that is supposed to help, but I want to learn what causes it.

Use fat free milk. 1 part milk 9 parts water. it does work ... DO NOT MIX IT STRONGER.... IT WORKS GREAT..... IT IS NOT THE FAT IN THE MILK THAT KILLS IT... TOO MUCH OF THE OTHER AND YOU WILL HAVE OTHER TYPES OF FUNGUS PROBLEMS FROM TOO RICH OF MILK...... WE ARE 100% ORGANIC

Use full milk... not skim milk..... the difference is substantial...

For the Powdery Mildew I'm trying two techniques to see which one works best on my papayas, beans, and Japanese eggplants that are all suffering. 

First is compost tea w some Maxicrop added in, nothing conclusive with the results so far.  I've sprayed it twice, once being only last night. 

And second is a mixture of 1 part Skim Milk, and 9 parts Water - which worked great, didn't wipe it all out, but quite noticeable results.  I want to run the coarse w the Compost Tea for awhile and see if that alone will take care of it, or if I also have to use the Milk spray.

Old thread but great information and perfect timing for me.  My squash has been suffering from a powdery mildew after moving them to a treed location that shades them in the afternoon.   Will try the proposed solutions above and cross my fingers!
