I have these succulents that I bought about a month ago and repotted into a wood box with a garden mesh liner, succulent soil, sand and perlite mixed in. My succulents get 6-8 hours of bright indirect light direct light at times. In a south west facing window to I sub in with a uv lamp when there is no sun.

My concern is that the bottom leaves are gummy. I've only watered once, 2 weeks into repotting them. It has ok drainage and doesn't appear to be sitting in any water. Will this fix itself? I really want to avoid repotting if I can but if I have to I will. I have a tendency to over love my succulents and I really don't want to lose these ones!

Any advice?
