I will definitely try to repot them. I have repotted this orchid before and I even have a healthy keiki from it that's a year old at this point. Something happened over easter while I was away, and I'm not sure exatly what - I don't know if too much nutrion might kill off the plant, but something did.
Thanks for the thread tip and the reply! Hopefully my keikiis survive this
Don't know if these images tell anyone anything, but I'll post them anyway
