I am using the undercurrent nute line and sensi grow with conniseur bloom. It would be much simpler to premix a very concentrated amount in 1 gallon of water. I know if I mix the nutes together without adding water the chemicals will react. So whats the Max PPM I can mix in 1 gallon of water for each of those nutrient lines? Dont worry about the plants my drip system activates a small pump that ensures the ppm of my res is safe. Just not sure how concentrated I can go without ruining the chemistry.
