Schultz plant fertilzer

Does Schultz Plant Food Plus have chemicals in it? Or is nitrogen, phosphate, zinc, etc considered natural? I want to water fertilize some of my herb seedlings but I don't want to use this stuff if it will make me glow in the dark.

I consider it an artificial chemical fertilizer - I use it only on house plants which I consider an artificial culture. I would not use it on the garden or anything I planned to eat

I use fish emulsion or compost tea for watering things I eat

These are my guidelines - others may have a different idea.

Thanks roxroe, I kinda thought that way too but wanted to make sure.

I have found, even things that say "Natural" or "rich in Organic Ingredients" don't fit my bill to be used on something I want to eat!
