Hopefully this is the last noob question I have to ask for a while. I just wanted to be careful not to over water. For now, I have just been spraying with RO water from a spray bottle for my new seedlings. This particular one is 8-9 days old now. Has the second node sprouted? If so, I was planning on giving the plant her first full watering (I'm using FFOF so no nutes needed yet).
