Here ya go. There's not much left in the pot, as I have rehomed a few succulents that were taking over. The succulent in the background is all that's really left, the stragglers on the right are what's left over from bringing inside during the winter and I am going to propagate them soon. Also ignore my hand, that was there to show the height the other day when I sent the picture to a friend. I'm thinking I will just be more careful about overwatering as many of you have suggested. And I've removed all of the affected leaves. There seem to be no signs of pests, initially at least, but I'll keep a careful eye out. Lastly, the skewers in the picture aren't necessary to hold the plant up, the trunk and limbs are firm and heathy and the plant stands alone. I just put them there to help control the direction of growth.
