I  got this Fiddle in the beginning of August, and slowly started to look sad, couple of days ago, I was wiping the dust off of my plants and as I was doing so, one of the fiddle stems came off so easily. Assuming I overwatered her so I separated the roots and replanted what I have left into a smaller pot with cactus soil mixed with compost. But two leaves (last pic) look blahh, burnt on the tips. Do I cut them off? What can I do to save it? Is this stem even savable? Or should I just give up and toss it? HELP!
