What are some good sources of both macro- and micronutrients? I switched to 12/12 yesterday, and so i will need to get some higher phosphorus to my babies. I'm kind of strapped for cash, so I'd rather try to find a source of essential nutrients from somewhere other than chemicals at home depot, lowes, etc. I have very slight yellowing of just a few leaves in just one plant, so my balance is fairly good now. But yeah, I've heard of stuff like molasses, etc. Any input is greatly appreciated!
