The little "bulbs" that are forming are the flower buds.
These plants for me have been plants that bloom spring and fall as daylength changes. They need a few hours of sun per day to help produce healthy growth and flower production.
They are succulents so the soil mix sounds pretty good. Since they are succulents, they do not produce deeply penetrating root systems. I would water it to a depth of an inch or so, then let it dry out between waterings. You may be watering either too little or not often enough. The leaves start to shrivel over a longer period of low water. But if you increase the frequency a little bit they will perk up rather quickly and within a month or so the plant should look a whole lot better.
