Deficiencies that start low indicates a mobile nutrient which should give you insight about what elements to look at as culprits. As to what stays in the media I would think would depend if you practice the 10% runoff rule or if you drench it like traditional hydro. From looking at the way Doc's kit progresses, I see he amends his mix with the N, P and Ca natural elements for slow release via microbes, but also he puts in some syths too for quick release. All must cook together with 30lbs of EWC to establish the microbe colonies and stabilize the nutrients in the media, so to recreate some of that effect with the soft rock, you'll need microbes to break them down over time. So if you don't have the EWC or can ensure there will be the microbes in the media, just hold the SRP on the shelf for the time being. I just whipped up my best attempt yesterday with the 30lbs of EWC. I screwed up and ordered just regular RP which is only 0-3-0, whereas the SRP is 0-20-0 with an added 20% of calcium. We'll see if my first crack at amending soil is worth a shit.
I just noticed you got 5lbs of SRP. Did you order that from down here by chance, or up there? I only searched Amazon for SRP, but only found RP. I didn't want to order 50lbs of CalPhos and was hoping to find 5 lbs of the SRP to try out.
All in all though, after the brix kits are amended, colonized and "cooked", the feeds are hydro from that point forward. The drenches are made from nutrient salts, Fish Hydrol and in some cases kelp. The sprays are the some of the same contents.
You might do well to adopt a foliar spray to supplement any shortages? With no real rhyme or reason to guide me, with my sprays I want to give the top 5 elements about equally, but in the neighborhood of 20-30ppm each so ensure I don't burn the leaves as I don't know the limits for foliars and don't want to learn the hard lessons. I've been spraying now for about 2-3 months and if I exclude all of my other experimental damage, the sprays I believe are helping to smooth out any bumps.
