definitely something wrong. I see the definite mite damage, were the plants covered in webs? The drooping in the first pic points to another problem of some kind. I am having trouble identifying it though.
What kind of light?
How far is it from the plants?
What type of grow system? (any details are helpful)

I am guessing there is a light issue but, give me some specifics and i am sure It will be identifiable.
