It all depends on how severe the damage to your succulent. While you can do it and watch how the succulent reacts, it is best to not take too much risk. So how do you tell if succulents have been too watered? You won't cause any harm to your plants if you don't water them for two or three extra days. But, if you water while the soil still has moisture, it could lead to root rot. If root rot is severe enough to affect the upper parts of the plant, you will notice signs such as discolored or mushy foliage.
