What nutrients or fertilizer would you recommend? I have been using Espoma Organic Liquid Tomato Plant Food,1-3-1 plus 1 calcium.
Research Korean Natural Farming techniques. They teach you how to make 2 very easy and quick to make fertilizers. 1 of them is a lactic acid bacyllus solution using cheese making techniques and milk (LAB solution). The other you can make a fermented plant juice fertilizer (FPJ or FFJ). Both use brown sugar to make.
I think the fertilizer problems (along with everything else) will just keep escalating. And people who are dependent on the store are more vulnerable. It feels good to learn to make fertilizer.
I don't have anything against commercial fertilizer because you need those to transition to your own techniques because it takes time. Also if they were to try to fix the entire agriculture system and what was wrong with it it would take such a huge effort that they'd need gap measures like chemical fertilizers because too many people don't know how to do things healthy anyway.
So you could use a normal chemical fertilizer while learning how to make and use a KNF LAB and FPJ solution.
