Thanks a lot for the information man. I bought some roots organics buddha bloom and have been using elementals for cal mag. The elementals is really difficult to mix well, and there's always a little bit of the white, nasty fish stuff still floating in the water when I feed my plants with it, hope that's not a problem. So as long as I add cal mag to my r/o water, I shouldn't have to worry about the ph fluctuating and getting too acidic? The reason why I ask is because the problem kind of progressed, but mainly on the same leaves, they just look way worse. How long does it take for the cal/mag to kick in? I've been using it for about a week now. There's definitely other deficiencies happening too. You're right about that.
This is my 4th grow using fux farms and I've had good luck with it, but I'm not going to use it again. I didn't realize they had quality control issues. I am working on getting a soil ph meter next, but most of my plants are doing great in it right now, just my biggest, hungriest one is having problems.
