as much as I don't want to say it. It might be like most people are saying I had the exact same thing happened to my Beautiful Kru! I hope you can salvage it!
Kru just after planting end of April 2011 ( it wasn't growing for a few weeks before ) but after planting it looked healthy right? 2 1/2 weeks later I pull on the p-stem and it just comes off and nothing but mush.
