I didnt read the whole thread with detail, I was just curious about that stuff. I was not challenging you Latewood, relax. All I was doing was confirming that using just 3 part was the best way to go, and using a lot of additives is taking focus off other aspects of the grow. Understand what I am saying? As far as my questions, I didnt read the whole thing in depth, sorry if I missed that part about ommitting grow, I was curious of your response. I personally use grow all the way through because Micro is more expensive then grow so by ommiting grow, Im using a lot more Micro. I get the grow for very cheap. Ive used Advanced with great results so thats what I continue to use, I aint saying GH is crap, just that I found it to be less concentrated.

PS. I only mentioned the PPM of our water so people know you dont need to use RO and waste a ton of water in the process. Obviously for many people, they do not live in an area where this is possible. I am blessed with perfect water that never develops algae and has no deficiencies. Im not argueing your "forumla", Im stating that all you need is 3 part.....

peace
