I know this is old post , bit I presume I can do this to my roots original soil?, Amend to full living? I have a fresh bag I want to do that to and switch this round over from liquid org.No blood meal. Good. Reading post1 that's all I was gonna suggest. I've been growing organic reusing the same soil for almost 10years now, and Alfalfa is my main N in the mix, along with everything else you have in there you should have enough different forms of N to never have a prob with green healthy plants. A thought for you; Nitrogen fixing bacteria pull N from the atmosphere which is mostly N. Grow those microbes! You know when you water and the water is flowing down through the medium, it is pulling air in behind it, air rich in N, but only unlockable by certain microbes. High Nitrogen fertilizers are not needed as much as you'd think, when growing organically. The plant takes care of itself.
I have on order kelp, humic. Bone meal, ewc, dolomite (I use ro water), bat guano bit wondering if I need it now. Maybe bird guano for flower? And wondering if I need langbenite in my mix I don't feel like I have any K in the mix. I cancelled my blood meal. Was going to add alfalfa or crab
