After reading this I can't be sure why your plants are experiencing a deficiency. It could come down to the soil not being alive or sulfur as you say. I have never considered how balanced my soil was when I started organics. I ran with cootz recipe and after initially making the soil, I only topdress if I see the start of a deficiency (usually calcium, and I just topdress with gypsum). I topdress at 1 tbsp per 5 gallons because I feel less is more and I can always add more later, and If I see an abundance (rarely, mostly nitrogen) I can switch to a different organic substance.
Based on my growing style I would still go with the rockdust and gypsum. I'm not sure why you are thinking of adding DE? care to share?
I have never experienced a sulfur abundance but I have had a deficiency once (no more thanks to gypsum ). I only have alfalfa, kelp. neem, crab, and gypsum/rockdust in my grow room arsenal. Get rid of the epsom and cal-mag, Bad juju lol
I was under the impression that DE contained various trace minerals, cal mag phos fe zinc, but DE is mostly silica.
Maybe I'll see about picking up some gypsum.
Thank you!
