did you flush your coco first. i got screwed and didn't know better with some coco mats and it ph'd so hi it burned my roots off. check ph of whats coming out of bags! most manufactures they say they're flushed but do it again anyways
 
hmm so the water turning brown is bad? lol .. thanks alot man ... is using coco in an ebb and flood system a bad choice .. or would i be better off with hydroton?
well just a newbie learnin so any help is appreciated - thanks man
