I chose to go organic over a year ago, I started using earth juice liquid nutes.. but I wanted to further my organic journey so I tried to switch over into the real organic world using castings, compost, and amendments like bone and blood meal. I learned the hard way that they are two different monsters.
The liquid organics are.. still bordering the line of synthetics if you ask me.. You are not relying so much on an active microbe / fungi population, instead you are relying mixing different organic nutes from different bottles to try and feed your plant what it needs for the given part of its life cycle. You can easily give too much of one thing or not enough of another, and it is somewhat still up to you to provide that for your plant.
From what I gather now, with real organic nutes, you mix what the plant needs into the soil, then the microbes / fungi break it down and make it available as food for your plants. they do it in a much more natural way, allowing the plant to pick and choose what it takes.
Be cautious confusing the liquid organics, with the dry organics. (That is my warning, I made the mistake myself) From what I read, the chelates that are used in the liquid organics, are actually bad for an organic grow and can do more harm than good, especially to your microbe / fungi's.
