Cabomba help

[Julianciraco]

Hey guys I bought some green cabombas and some purple ones. I put them in like last week and now the purple one is GREAT! But the green is like not even opening up, falling down as if the stem is broke and idk if I should cut it off or what I need some help with what to do, I wanna save this plants I love them.

Pull the green ones up and cut off any bad bottoms on them. Then float them until they develop some roots and then replant them.

It's not really possible to even approach this problem without knowing about the entire tank. Water parameters, lighting, fertilizers, and co2 can all cause what you're describing.
