If you don't mind, I'll give you some suggestions instead of names...That potting soil may be C&S, but IMO is very fine and possibly water retaining. If you have bag it came in, pls. check ingredients. If there is large % of peat or "forest products" - it will not work that well for succulents. It needs lots of amending: at least 50% of total volume (if not more) of sifted perlite. You used glazed pots - which wouldn't be much problem, but they do not breathe as well as regular terracotta pots. So together with dense soil, there could be water retention problem.

It is very important for succulents to be in well draining potting mix. They don't even need soil - many of us are growing them in mix of gravel/grit, some perlite or pumice, and maybe little of bark or turface. There are other combinations of different substrates that could be made to get a well draining mix. Using lots of inorganic matter helps a lot. That kind of mix will allow you to water well when needed, and any excess water will drain out rather than saturate soil and keep it wet for too long.

Next important thing is lots of light. If that is not supplied to succulents, they will grow stretched = etiolated, with weakened stems that eventually can't support themselves, and the color is usually too light from lack of sunshine.

So regardless the names, providing excellent drainage, watering well but only when substrate is just about completely dried up and supplying lots of light are all very important for succulents growing well.
