Micronutrients are all too high, especially the boron. You do not want these in the 'very high' range, it will cause lock out. You wanto 'very high' in the macros like N, P, K, and Ca. Nitrogen is low in my opinion, the other macros are really high. Organic matter is way low, should be at least two to three times that.
Ditch the Foxfarm it's garbage and probably where your excess micros are coming from. They tend to use a long of filler in their junk.
Balance is key. Do not want to have excess.
Not that great of a start,compost was used in excess.
Low calcium, excess Mg and K.
S and Trace minerals are in excess.
PH, Sodium and exchangeable hydrogen is not shown.
Where did you get the soil test done?
FYI< That soil does not need dolomite, Tiny bit of ag lime and then ag gypsum. Would better to start out with better proportions and lower Mg and K. Do not forget sodium.
If you want to try again and get better results. Mix the promix, ewc and aeration. Test the soil. Then add what is needed.
I see why now, you are using spectrum.
Spectrum Lab: trace minerals will be higher and usually lower levels on Si and OM.
Comparing the first pic and then the test you posted. First test 947 Sulfur and then next report 1947 ppm. Little inconsistent.
You new mix sounds like a better base.
Way better. Excellent! Good job on following directions. IJust wanted to let you all know that based on the comments above, I mixed up a fresh batch at 7:2:1 of Promix, Castings, Pumice. Sent it to Logan and here are the results:

I think this gives me a much more balanced base to begin adding goodies. No compost in this mix at all (maybe trace amounts from a few handfuls of recycled soil)..
Thoughts? Am I close? :)

The desired values are based on the work of Albrecht. He studied the relationship between soil and human animal health for over 30 years. The ideal values also create the ideal environment for the microbiology.Looking a lot better! I'm still learning about soil nutrient balances though. What are the "desired values" based on? Is it a general standard, or something you provided? That 6:1 calcium/magnesium balance looks great (from what I understand it should be), although I'm curious if others will confirm this as being correct.
If you wanted to make up that deficit in a safe/low-impact way, maybe an addition of some oyster shell would help? Would probably raise the PH a little too, and then slow release the cal/mag.
The desired values are based on the work of Albrecht. He studied the relationship between soil and human animal health for over 30 years. The ideal values also create the ideal environment for the microbiology.
Shooting for calcium to be at least at 68%, 12% Magnesium, 4% Potassium and 1.5% or less Sodium as far as cations.
Add cations will raise the ph. Not solely calcium carbonate.
Shooting for the first 60% of calcium to come from calcium carbonate. The remaining 8% to come from ag gypsum.
So not a good idea to add oyster shell at this point. Time for Ag Gypsum.
Then work on balance of microbiology. Bacteria, fungi, protists, nematodes and microarthropods!
Hope all is well.
