If it has kelp, mollases and bone meal there's no way it has zero nitrogen unless they are processing it in some special way and since it's a 20 year old product I'm guessing that isn't it. Is this why my plants stay green when I give this from flip to finish? I know slow release things don't have to be on labels but shit gets confusing especially when other countries are involved. Any Thoughts on the 3 listed ingredients I mentioned would be greatly apreciated.
