I think it dried out a little too much. It perked up after I watered it. I will do the watering every 2 days instead of 3. The soil drains well into a saucer. The plant is still green and getting very slightly bigger. No sign of a 2nd node, though. I will just keep ig going and see what happens. I the mean time I have several dozen bag seeds left, and will germinate some more.
