I've been having major stunting problems and I think I might have finally stumbled on the answer. I was using that Ph down and Ph up for aquariums to adjust, but just read where that stuff contains too much salt and not to use it on plants. So, I'm wondering how much baking soda for up or how much vinegar for down I should try in a certain amount of water to adjust Ph. I'm thinking severe lock-out by now. What's the scoop on that Ph deal?
