Very helpful guys, thanks, but I have another question. Zandor says I can add CalMag if I am using RO water. Why can't I use it with well water? Should I just take it back? And how much Liquid Karma and Calmag do you guys add per gallon? Do you stick with the instructions or vary that? I am using Tiger Bloom for the basic flower nutes, if that matters. I would be happy to supply specifics on the Tiger Bloom if that would help, but I am leaving in a few minutes for 2 days.

However my plants in the flower section started exhibiting some small signs of nute problems, so I broke down and bought a PPM meter. Now how the hell do I use it? I think I remember that PPM should be about 1 to 3000. Is this right, and that's a big difference. What's best on average? And if my PPM is too high, I just use less nutes, right? And I bought some Liquid Karma and Cal Mag. How do I Rating: 5
