nute burn...i think ... abd drooping n twisting of leaves

I am growing in ff under a two foot four bulb t5 for a 24 hr time period in a 62 x 36 x 20 grow closet with an exhaust fan and to small fans of an unknown strain of mj. I added 10 ml of cns 17 nutes inside of a liter of 6.5 ph water . After about two feeds in about a weeks time the plant showed signs of nute burn so I flushed it. Now it looks to be drooping and twisting in to a ball (the leaves) I only watered when the soil felt dry. Any help would be great. No Pix yet but will post some
