San Pedro Cuttings: Someone knowledgeable please look at this pic

[preshadrop]

Hi,
below is a pic of SWIM's san pedro cutting, it's been growing in a pot for a couple of months. I thought the actual cutting would start growing once roots had formed, but its just producing this little cactus on top. The actual cutting is meanwhile turning this weird brownish colour. What should SWIM do? Maybe take the little cactus off somehow and plant that, saving the big cutting and freezing it? Help!!


BTW, SWIM says the cutting HAS formed roots... he's not sure how big they are by now though as he is worried that he will destroy them by checking. He also has the impression that the cutting is getting softer.

Any advice much appreciated!



Here is the pic again.
