root

G'day All, I recently struck a seed using the paper towel method (can't beat it!), and when I was transferring her over to her new home, I noticed something unusual on her root.. I am just wondering if anyone has seen it before, or knows what it is.. She has broken surface, so it doesn't appear...

I was showing off my root system and noticed that there is a section that looks like it has brown sludge on it ... I also noticed that there was some excess air hose in my bucket so it was like coiled in there n pulled the excess hose out so it just runs down to the air diffuser.. everything...
