What Is Wrong With It
Yellowing leaves, brown tips, sudden drop, wilting that water does not fix. Sorted by what you can actually see, with the most common cause ruled out first and a timeline for how each one progresses.
Start from what you can see rather than from what the plant is called. Most houseplant trouble announces itself in the same few ways, and the useful question is rarely “what is wrong” in the abstract. It is “which of these three, and what would tell them apart?”
