Greenish IMO4 // trichoderma // pig pen

As part of a community project here in Otavalo, Ecuador, we've built an amazing raised KNF pig barn (w/biochar, logs, and cornstalks, with these covered by rice hulls (90%) mixed with soil (10%); plus the pen has a split roof, well-drained water nipples, etc.) We seeded IMO4 on top of the cornstalk layer and covered all this with 10" of rice hulls/soil. However, this was about 3 months ago! As we're FINALLY ready to bring in the piglets, we've begun spraying the corral with the "protector" (LAB), "food" (FPJ) to activate the IMO4. Sea-salt water sprayed on as well. Me, being worried that the 3-month-old IMO4 may no longer be effective, I made up a new batch of IMO4. The problem is that the little IMO4 clumps have a faint aqua-green color, which I assume is trichoderma. MY QUESTION [no. 1 of 2]: Is the second (greenish/trichoderma) batch of IMO4 bad?  ...meaning unusable for a piggery Gracias de antemano..!!
