the one thing I don't understand is how to use the TDS meter, the last time I tested it the nutes, I got a reading of 64 I think you have to multiply by 10 = 640 so what do I do now? I don't know if I have to add more water or nutes to the tank, I would appreciate it if someone could explain to me how it works
