My first thought it had better be cheap or have other effects than just minerals for your plants. Does it act like a plant hormone? if so which one?

The chloride number is high in relationship to all the other minerals. I would ask the question if you need chloride what about sea salt. I know it can really add a lot of energy to the soil however to much can be a very bad problem to have. Chlorine can be very difficult to remove from the soil if you get too much. If you use it please post a follow up on if you think it was worth it.
