In the first image you guys can see one of my oldest plants (≈2 y.o. at the time I only had her and a pineapple plant) I need to say this guy is very resilient, and it don't complains at all, it simply starts to abort his own roots.
I took care of her like a normal succulent whatsoever, but at some point I got a heavy hand for watering and needed to replant it in a smaller pot because of some root rot.
After that I think I never saw her happy again.
Since I moved, it's in my West facing window (Southern Hemisphere) and received one watering. After 5 days his soil wasn't dry like I would like. And a quick root inspection show that the roots started to rot.
I'm replanting it in a 80% inorganic, will be in my east face window until it settles down again, and back to the sun after it.
What am I doing wrong? I would like to see her happy again like in the first image!
