Sure, short on Iron? drop a nail in there.
Want a female, add a birth control pill the the germ water.
Want more dissolved oxygen? add hydrogen peroxide.

WTF man. Why not just use what is proven to work. Its only a weed.

I know you are only asking but hydroponic supplements will give you the correct amount of supplemental nutrients instead of guessing.
