Carcinogenic ingredients in nutrient formulas?
I'm shopping for nutrient products for my hydro tomato project, and I see the MSDS (Material Safety Data Sheet) for a product from General Hydroponics. And the warning indicates the product may be carcinogenic and affect organs. Is this just a general warning that comes with all fertilizers or something unique to hydro nutrient liquids? What exactly is the carcinogenic material in the product? What sort of safety gear do you all use when handling these nutrient products?
In researching how to make my own nutrient solution I noticed some form of chemicals used in nutrient concoctions can be mutagens. The General Hydroponics product linked below doesn't seem to have any listed mutagens though.
