So I saw that my new roots starting growing above my medium (hydroton) a little bit... not much... just little nubs. I read around on the forum and saw that meant they were root-bound. I figured that must mean not enough oxygen since I'm in a bubbleponic system. I then checked and saw that one of my bubble pumps had become unplugged. I don't know how long ago it came unplugged, but other than the nubs, the plant looks healthy. Is this an issue? How much do I have to be freaking out right now.
