I have been growing these plants with 2 bubble rings and
change the water every 2 weeks.
After the last change, I managed to damage one of the plants root system. The other is growing very fast.
My question is , is it normal for the bottom leaves to fall
off when new growth is sprouting from the node. Can I
cut off the parent leaf after the new growth has started
and the old leaft is dieing?

As an aside, I would love to know how to post pictures.
Thank You.
