my plants love RO, i use there nutes an there soil. theres a few diff kinds of soil they make so maybe those of you that dont like it dident buy the correct one for your goals. theres a mix that has a much higher N content to start with then there other one that you can fill in around with when you uppot before flower. to the guy that said its nearly as bad as MG, if thats the case im switching to MG asap cuz MG is hella cheap. (kidding)
yeah one moment he hates roots and now he's switching from FF to RO soil haha. im not sure whats up with him, but MG is awful!! haha
