I think the electrolytes (calcium chloride, magnesium chloride and potassium bicarbonate) are bad for your plants. I wouldn't use it, but you could always take a clone and let it root and try watering with that and see if it works. It might be a good supplement for after flushing. Help it re hydrate and quench it's thirst.
