Lab J32362 (w17) is what is in the bed... I don't know if you received the results on that one...
Yes, start your own thread and post your results.

Led, sorry, can't help you on the CO2 influence. Surely there are a bunch of guys on this thread that can chip in....

Guys, I dont have my Spectrum results back yet but based on earlier analyses I'm expecting to see high K, insufficient Ca and insufficient available P.

Way back @Avenger mentioned PSB. Wondered if anyone has used Tainio's Spectrum PSB

Also curious about the usefulness of BioMin Ca powder.

I have a simple, small garden with a few 7 gal pots, using recycled peat based media.

Happy Holidays all, I got my post grow soil results back. Had a great season. No bugs or mold and the plants looked great. They were a little bigger than last year average 8'x7x8' and looked healthy all the way through. Buds turned out very nice. However the weigh was less than the years previous.
Looking at the soil tests I believe part of the reason the weight wasn't there was because I did not amend with much N at all this year hoping I could supply it with pure protein ( fish powder and vegetable powder) during the grow with foliar and soil drench. Plants looked great but I don't know if that is the best way to go. I know it sounds crazy to say low N affected flowering and it might be let me know your thoughts.
Secondly I noticed my soil took a long time to dry out and it made it more difficult for me to make corrections. I plan on amending with twigs and bark mulch and looking into coco chips as a local place has them for a good price. If anyone used coco chips before I'd love some feedback.
I consciously tried not to use anything with much Mg this year but my levels keep going higher this year. I did use gypsum this year hoping to increase my Ca and decrease my Mg but it looks like only my sulfur went up. My K is a little higher than I would like it and my Mn Zn cu are a little lower than I thought they would be after amending with micros all season. I used chelated minerals maybe mineral sulfates would of been better or showed up more IDK.
Anyway thats it for now. I'll follow up later when I have more time to compare my results with tests years back.
Cheers

This paper is loaded with interesting data relevant to Ca uptake





Phosphate-Solubilizing Bacteria Nullify the Antagonistic Effect of Soil Calcification on Bioavailability of Phosphorus in Alkaline Soils




Conclusions

Inoculation with phosphate-solubilizing bacteria (PSB) neutralizes the negative effects of soil calcification on the bioavailability of soil phosphorus (P) from mineral, natural and organic fertilizers. PSB released varying amounts of Olsen extractable P from different P sources during incubation. Soil amended with organic P sources released notably higher Olsen extractable P than SSP and RP in both inoculated and control treatments at all incubation intervals except day zero. PSB viability tended to decrease with increasing lime content; however, organic sources of P better supported PSB growth even with increasing lime content. These findings suggest that PSB increases P availability from organic (FYM and PM), natural (RP) and mineral (SSP) P sources in calcareous and non-calcareous alkaline soils. To improve P nutrition, efficiency and crop growth, P should be supplemented with organic sources in addition to PSB inoculation in alkaline and calcareous soils.

Way too much K in there, some bone meal may have helped had you got it on in time. .

With all that Mg and K, this is why that soil took forever to dry out.

No way that you will see much if any build up of micros using chelates. It usually takes some large quantities of sulfates to achieve balance.

Yes I agree on the k and Mg, I don't know why my Mg is so hi as I stayed away from it all season.
At the beginning of flowering I soil drenched with liquid bone meal from a tank with constant agitation and also top dressed with seabird guano 12-12-2 as I do every year.
Maybe because I used extra gypsum this year during veg and beginning of flower and used Ca from baicor in my foliar sprays all that extra Ca created more space for anions and it required way more P to fill the space for maximum potential. IDK i'm still tying to figure it out.

Do you have a water analysis by chance?

That is where all my Mg comes from, my water........ It hurts. I got back my soil results. Let me see if I can load her up.....
