My plants leaves are looking terrible

Hey guys what do you think is wrong wit my plants? The bottom leaves are wilting and the top leaves jus look really burnt i dont know what to do? Its about 3 and half weeks into flowering. P.s does over nurishing them have anything to do with it?

Over nuting them is my guess. How much did you give them?
