I’m steadily taking steps to improve my techniques and develope my skills. Everyone started somewhere. I just figure auto or photo soil or hydro, indoors or outdoors. I still have the same water for all. And when I cleaned my automatic bases reservoir it had white limescale buildup after only one week. That’s what solidified my claims and I was curious if cut out cal mag how often should I add Epsom or magnesium or should I at all. Cause I have been adding some on feed day just mixing a lil in with feed.
