the first thing I noticed was that your soil is too dense .. meaning it (the soil) is holding too much water ...too long
pull the entire plant from the pot ...and mix in more perlite, rocks, pebbles and sand to make the soil more "chunky" .... try to sift out the fine silt so you have a predominantly gritty potting medium ...this will be a faster draining, less water holding mix
