Recycled soil tested after 1 year

I thought this was interesting and maybe worth sharing.

I've been growing indoors using recycled mix for flowering for about a year. This is the Soil Savvy test result from the initial mix when starting first flower cycle

And this is the test I just got back

During the past year using this mix I flowered 13 females for 70-84 days, and 9 males which I cut at ~21 days each, plus 4 days between final transplant and starting 12/12 for all plants. The only additives I used were

- a little greensand and glacial rock dust after the first plants came down, to try and bump up what looked like low micros.

- I topdressed two 'hungrier' looking plants this year with 1:1 soil mix/EWC plus 1Tbs of biolive or alfalfa during week 3ish of flower.

- Two of my storage totes got 5tbs each fishbone meal and feather meal maybe 6 months ago. That's the mix I just had tested and am currently using

- I veg in 1g FFHF + a small amount of EWC, maybe 1/4 cup or so added there

Otherwise my grows are water only start to finish, and then I add some EWC to the broken up rootballs while they rest. I've got 4 little totes maybe half full each that I rotate through.

I don't push my plants. Short veg, I don't train them or blast them with light, etc to try and maximize yield. So I get why they might not eat that much. But really it seems like even the little I did feed/add over the last year was maybe too much, in that the numbers are creeping up.

Right now I have two at ~30ish days 12/12, in the same mix I just had tested.

Most do just fine and I'm happy with how this is working so far.

Neat food for thought!
