Probably wouldn't even need the extra amendment now that I think about it. 10lbs EWC instead.
If go get another fresh bale to cut this used soil with, but my office already has two bales in there in different stages, and I could probably spare 30 gallons of fresh first run if the second run mix would be done cooking in a month.
Kinda weird to skip the first run, but in the end it's almost better, don't need to buy another bale. Trying to think how two bales and two kits could be best used to maximize the magic. I've started in on half of my fresh mix to veg the next round, they'll go for at least a month, plenty time to cook the second run and be ready to use when this round of plants are ready to flower.
In light of new instructions, I can get sunshine #4 for quite a bit cheaper than promix around here..anything worth noting? I'd be much happier saving some money, if the results are identical. I'd use that to cut my recycle if so.
