My phal got what I thought was one keiki on the stem.. When I cut it off I realized it's actually two keikis, growing in the opposite direction of each other (connected by the "mother stem"). They were still so small so I planted them together, but now they're growing quite rapidly. Especially one of them seems to feel very well, with a new stem growing so fast you can almost see it growing, but the other one seems to have stopped growing because its stem is growing down towards the pot.
Here are two pictures of them (taken two weeks ago, the stem growing upward is about 2" longer now)


Any ideas what I can do? It's impossible to see which roots belong to which keiki and I really want both of them to live...
