Is there any way my Peperomia can recover?

[Kaeguri]

Hi everyone! Brand new here and I have a major case of brown thumb, I havent been able to keep any plant alive for more than a few months. It's been a couple of years since my last guy and I decided my heart was healed enough to try again and I opted for a cute peperomia.

So I have presumably overwatered my peperomia, I think this because I had a little one in the same pot too that died of root rot. (Did cut off some of it though and currently trying to root it)

Now my pepe (that's what I call him) that's left has this going on at his stem, turning dark purply/black. Is this blackfoot? Can he recover? Since losing the little one, I have changed his compost (google said a cactus and succulent mix would be ok, so I went for that?) and no watering until hes fully dry.

Is he gone forever or can he heal and recover?

Greetings, welcome to the Forums.

It is hard to judge the qualities of that discolouration with certainty. If it is firm and dry, your Peperomia obtusifolia may be fine.
However do take a cutting as 'insurance'. Peperomia root very easily. In the future, repotting into a faster draining soil mix and/or watering less frequently will place your plant in less risk of rot.
