I’ve had this succulent for more than two years now and a few months ago it was slowly losing its leaves until it became the size that it is now. The leaves that come off would be mushier than the other leaves and yellowish. Is it related to the white marks? Not sure if it’s due to over watering, but I took it out of its larger pot to see if it is root rot. I have another succulent that is doing very well so I’m confused why this one has been declining. Would very much appreciate any insight or advice! Thank you.
