Hi, All - this is a picture of my only two cuttings of Frosty Pink. See how the top is shriveling and browning. That brown area seems to be creeping downward. Is it rot? I noticed it earlier and I cut off the tops that had just a little of this brown area. ..but it's coming back. Anybody know if I can save these? The bottoms had formed good starter roots in water and are now in these little pots and seem otherwise to be fine.

Advise?
