Powdery Mildew with only 10 days until harvest! please help

Hey,
This is my first post, but I have gotten a ton of info from this site. So thank's in advance.
Basically I just did my first end of harvest flush 3 days ago, and I am going to do another today. Depending on the weather I will probably harvest in 7-10 days. There is a small chance of rain, its in the low 70's (temp), but so far its been dry. The plants are looking great, other than powdery mildew. It had to have sprung up overnight, I pay good attention to my plants, and I didn't see any of it yesterday.
I am just wondering if there is anything that I should spray on them when they are this far into harvest. Or if I should just cut off all of the infected leaves, hope for dry weather, and harvest. I don't really want to spray the buds and risk other diseases caused by damp buds. Hopefully I can just cut off the leaves, because so far there isn't any mold on the buds that I can see.
Any suggestions would be very much appreciated. I have read about all kinds of sprays you can apply, but I'm wondering if its even worth it this close to harvest. I'm not sure how fast it spreads.
Thanks

try and remove it:rastasmoke:

If you're that close to flowering, cut off the leaves that have it. I hope it doesn't spread. :thumbsup:

A very common natural remedy for powdery mildew is diluted baking soda in water...sometimes people add a drop of liquid soap to it or horticultural oil but if I were you I would just try maybe a half a teaspoon of baking soda in a quart of water with no soap or oil....you can spray it every few days to check if it is burning the leaves or anything. that's what I use on my roses and it does kill the mildew. Good luck.

Just google natural remedy for powdery mildew.
