This is like asking if the vitamins that you give to a chicken as a chick will poison you when you eat it as adult, I am not talking of hormones or growth agents, just literal common vitamins

You don't eat "the vitamins" you eat the chicken, you don't eat the fertilizer, you eat the plant

If you feed mercury to the chicken as a chixk, then eat it as an adult, do you get the mercury?

Life can create, modify, and break chemical bonds, but can't create, modify, or destroy elements. Vitamins can get metabolized into other compounds but mercury stays mercury.

This thread reads like a Monty Python sketch.

Because... fertilizer is mercury!
