I got this zebra a couple of months ago, it was doin great and one day I was bored and I got some leaves (made some cuts to get it) so I can try to propagate it, resoil it and I watered it that day too. Days after it had rotting leaves and when I checked on the roots, they were rotting too. I cut the rotting part (leaves and all roots) and left it out to dry and heal its wounds (which I know I should've done the first time it had some) put it back in soil and let it sit there for a couple of days before I watered it.

Now it looks like this. I'm not sure why the leaves are like that and there is leaf discoloration too. It's not evident in this pic but the inside leaves starting to turn light green/brownish. :( how can I properly take care of my poor buddy?
