Brown Leaves

[mdwaller]

Hi, I'm new to growing and can't find any images of what my tomato leaves look like. I am growing in 70/20/10 coco/vermiculite/perlite and feeding daily with general hydroponics 3 part flora series. I did just recently add subculture M as well. We have had several days of rain and very strong winds and the plants were not protected. Don't know if this could be wind damage or what? Any advice is appreciated.

Thanks!
