Thank you I just got nervous since the last two failed. I hope she takes off soon. Just worried me when I cut off the air pumps and saw 3 4 small floating roots that had broken off didn't know if that was normalHi jtrain, I believe you are correct that the brownish color is just nutrients, if it feels and smells fresh I would not worry. Your plant looks like it is about to start growing like mad! Keep up the good work.
