Clackamas Coots was my base recipe and I've been making adjustments according to my soil test results. I'm usually low in at least one micronutrient.
I started using compost again. I bought some soil from "Build a Soil" back in Dec 2016 and it didn't really work out, so I set it to the side and composted it for over a year with leaves, grass clippings, and rabbit bedding. This is the unmixed compost.

It's easier to expand the thumbnail pic. Anyways, this is pretty standard for my compost pile. I've been avoiding compost because of the high amount of phosphorus, but I'm starting to get the idea that it is something that I am going to have to deal with and always have to add Mn and iron.
Anyways, my last batch of soil ended having K def and I think that it was from too much Ca and Mg because I used a lot of dolomite lime and other rock dusts. That was the soil w/o compost and I'm not using it anymore.
I'm thinking about only using azomite and greensand in my compost because they both have a decent amount of Mn. I understand that the potassium levels need to be 2x the amount shown in the soil tests, the creator of the test talked about it on a cannabis podcast. So, I've been focusing on using less Ca and Mg and raising my K levels. Also, I'm trying to keep N levels down for a higher brix. You can compare this test to the one above and you can see how much sodium has raised by a moderate/light amount of kelp. This is the compost from above with 1:1:1 to peat, perlite, and compost. I added kelp, alfalfa, and neem meal also

Things didn't look too bad but the plants really were not happy. I mixed up some Mn, Fe, and Zn sulfate for a soil drench along with a fermented plant juice and things started to look better the next day. I also did a light foliar feed with mostly Mn and fermented plant juice because I know that Mn is not supposed to be very mobile in plant tissue. I'm kind of new to foliar feeding, but I have seen several people say that is one of the best ways to get high brix #'s. I really enjoyed Steve Solomon, author of the "Intelligent Gardener", and he suggested using BioMin Booster 153 during a podcast. So, I ordered it but it hasn't got here yet.
I always feel like I am close, but my plants tell me otherwise. I've been at this for over 8yrs now and I still can't get that perfect harvest. I had a perfect harvest about 2yrs ago, so I know what it looks like. I think that I just had some beginners luck and I am trying to back-track to see what part of it was right. I'm starting to think that it is the Greensand in the compost that made things right. I recently bought a 45lb bag of greensand because I feel like it is the piece of the puzzle that I am missing. I wasn't impressed with the last bag of Glacial Rock Dust that I bought. It looked identical to basalt, but I know that there is other GRD out there. The first time that I had GRD it was brown and micronized. This current bag is course and black/grey and I can't tell it apart from basalt.
Anyways, thanks for listening!
