weekly care

[WhiteRabbit]

What type of media is it potted in? If you haven't repotted the plant, the media is likely old, and retaining moisture. Are you checking the media below the surface for moisture? Poke your finger in and inch or so, or better yet, use a freshly sharpened pencil to poke into the media (the newly exposed wood will easily show if there is moisture by becoming darker) - or use a bamboo skewer in the media.

As for condition of the canes, can you post pix? Older canes will SLIGHTLY wrinkle. New growth should be smooth. Overwatering will also cause canes to shrivel/wrinkle, as roots rot the plant cannot take up water. If you haven't already, pull the plant out of the pot to check the roots.
