If it is on top of the leaves it is Powdery Mildew and a mix of baking soda and water in a mist bottle will kill it .
If it has started down under the leaves and is showing through then it is Downy mildew and Will need a copper treatment to get rid of it. At that point I will suggest go to the local garden center to see what is legal in your area to spread/spray by home owners

I've tried the baking soda and summer oil spray that the posted website says is experimental. It works. It works better if you put a few drops of dish washing detergent in with the oil and soda.
Powdery mildew needs an acid situation to get past your plant's natural defences.
This particular mix washes off in the rain very easily, and it is also countered by heavy smog and marine fog.

Sounds like you have a form of mildew accumulating on your plants. If you have a nursery in your area, take a sample leaf, stick it in a ziplock bag and have them check it out. Any reputable nursery can easily identify what kind of mildew it is and suggest what steps you need to fix it. Odds are they will suggest to use some form of fungicide. But you may have to remove all infected leaves, and one of the probable causes is that the air around the plant is fairly stagnant, and you are watering from above. But trust me on this, take a sample in a ziplock bag to your local nursery. The reason you use a ziplock bag, that way you dont pose the possibility of infecting any of their plants.

The symptoms sound like powdery mildew or downy mildew. Both can be cured with a fungicide or dish soap and water mixture.

Powdery mildew. Remove and destroy all moldy leaves. Buy cheap coffee and pour around plants (fresh grounds) water in with beer. Really. Cured my mildew problem.

They're minerals from the water you are using. Try buying some distilled water to use when ironing. Distilled water has most of the solid contaminants removed (like minerals) So that should minimize, if not eliminate, the white powder. You can buy it in the grocery store, they're next to the regular spring water so be careful to look for the word "distilled" on the label.

I just always assume that I need Hi Yield "Kill a Bug ll" and for good measure hit everything with the same. When I get the sprayer out to mix with liquid, it is no more trouble to get everything at once.It kills over 100 insects. I am very careful with what I put on vegetables, fruits, etc.....Ortho makes everything and is easier to find...http://www.ortho.com/

Hard to say without seeing it. Anything from contaminants/precipitate of the water to fungus, to insect activity.
The best way to check on what it is, I have found, is to pull a leaf, and take it to a reputable nursery for their advice. If you are near a college, that is another option, to take it to the botany department.
Best wishes.
