This method of gardening very much resonates with me
I am a big fan of enriching the soil itself and only including a few things, if any, in the water. I do like using hygrozyme and roots excel with some liquid fulvic/humic acids, as well as compost teas every now and then.
A few things that I've been using (to amend my soil) with great success are:
- Sango coral calcium powder: when I use it, my plants just seem happier. you don't need much at all, especially since it's got a very high pH... lots of calcium, magnesium, and tons of trace minerals
- "Mum's" brand organic vine-ripened banana powder: I've been using this to see how it compares to molasses for feeding microbes.. I personally think it's superior, and seems to boost microbe activity for a very long time. Again, a little goes a long way. If it wasn't organic and vine-ripened, then this stuff would surely do more harm than good.
- Rock dust, rock dust, and more rock dust (the more paramagnetic, the better)
- Zeolite: I water so much less when I throw in enough of this stuff.
I highly recommend you give these a shot, especially the banana and coral powder
