Hi - I have an unknown species of cactus that has been healthy for a long time! Over the past few weeks, he's been bending at the top more and more. The top part of the plant is quite soft, but the bottom is still firm, so I don't think he's rotting, and he is never over-watered. I turn the pot frequently to ensure full sun coverage. Any idea what is happening and how to help Buford?
Lack of light, probably in combination with too high temperature, has caused it to grow too thin and weak (etioliation). There is not much to do about that, except to cut off the top, wait for new stems to grow out, root them and grow the new plants in more suitable conditions.
