Wilting, Twisting, Yellow... Help? (pics)

Hey guys, so we just got 2 big old clones transplanted into a hydro setup and they are slowly deteriorating. Thought it was over-watering maybe... so cut it back... still going downhill.... thought it was too much nutes... replaced water... still not looking good.... lights not too close...

I put them back on continuous water and they are looking slightly better... but sill have a look and tell me what you guys think.

whats the ph and wat kind of water are u using and how many times u water and wat set up is that
