Allright. Time for Science! and no money!
If you do decide to bail on this soil, try an experiment if you can. Rinse any that’s been used & recombine with some native soil. Get it from an area that has an old large tree if you can but any healthy soil will be loaded with life. About 10% to 50%(if you have time time make separate ratios, i.e. a 10%, 25%, 50%).
Moisten & store out of sunlight for 6-10 weeks. When ready, try out some cheap vegetable/flower seeds or starts in your “repaired” grow medium.
I’d also recommend using a “drain layer” on the bottom of your pots(even fabric ones)-- put 1" of perlite, lava rock or clay balls and it helps keep the bottom of the soil from getting “boggy”.
I’ve read tomatos are a good test plant due to similar feeding appetites.
You can go forward using something else for cannabis while you wait for the microbes to work your dirt.
