I believe this is an echeveria. I got it maybe 6 months ago and transplanted it to this pot. It has regular potting soil and one thing to note about the container is that it doesn't have a drainage hole at the bottom.
In the past month I've noticed some of the leaves in the interior are turning a brown or dark rust color.
Why is that happening? What should I do to make this plant happy? (bigger container, different soil, more water?)
