How much water are you giving it with each watering? It looks like overwatering, but it can be saved if you let the soil dry out and reduce how often you water it.
If you have bamboo or wooden skewers, stick one all the way to the bottom (gently, and closer to the side of the pot where you won’t snag the roots). Pull it out after 5 minutes. The skewer shouldn’t be bone dry at the end, but it shouldn’t be too wet… It’s hard to explain but you’ll eventually get a feel for what seems right.
