I just transplanted one of my plants and on the bottom of the pot was coco chips to help hold in the coco coir above. One of the chips fell off and I saw this on it through a 30x loupe. I had issues with root rot back in the first part of summer but not in the next set that I just harvested. This makes me think I may have pathogens in my coco chips rather than in my coco coir. I looked it up on Google Images but couldn't find anything like it. What do you guys think?
