Did I kill it??

Need some hydro help guys......I think I may have killed a beautiful 8ft tall indica from flushing it. I did a water flush on it to flush salts, poisons, etc.....and ever sincs then it has been losing foliage and wilting badly. From the bottom up. The only mistake I can possibly figure is it was out of water for maybe 5 minutes. Any thoughts or experience would be greatly appreciated.

it has no nutes thats what its supposed to do, when did u start flushing what week is it where are the trichs at what is the ph lots of variables give more information
