Okay at least no oozing. You said you have it outdoors. Not knowing where you are, what is typically your overnight temperature? Some succulents can bear up to 30F to 32F as long as kept very dry, and oftentimes, that browning will manifest too if it is starting to feel too cold. At times when temps are cold, humidity is high. So not the ideal situation for them. They do get cold burn too.
