spidermites, thats whats wrong. you answered your own question. i regret to say, tear that shit down and start over, after cleaning the entire area thouroghly. get some clones, and you'll be back in business. sorry, but that shit ain't gonna make it. i think your humidity was low and your temps high.
get ur self some neem oil, follow directions on next grow.
