Hi Jookieblue, I was reading last night about effects of low humidity on plants, and maybe what your plants are experiencing is related to low humidity issues. Do you know your indoor humidity levels for this time of the year. I have been observing my plants as well, and have seen similar conditions on the leaves of some of my plants, grown indoors and outdoors. I think only my succulents are enjoying this low humidity season.

Spider plants though are toughies, I was just repotting one yesterday, and am always amazed by their very thick and plump root systems, so even if the leaves gets badly damaged, it readily gives out another.
