Not enough light
A polka dot plant that stretches and loses its bold spots is almost always under-lit.
Diagnosis
Not enough light
What's happening
The pink, red, or white speckling needs bright light to develop; in dim conditions the plant pumps out plain green to capture what little light there is, and the markings wash out. Low light also makes the stems stretch and lean toward the nearest window, with long bare gaps between leaves — the classic leggy look.
How to fix it
Move the plant to a brighter spot with plenty of bright, indirect light — right beside an east window, or a few feet back from a brighter south or west one, with sheer curtains to soften harsh midday sun. If your space is genuinely dim, a full-spectrum grow light is often the only way to bring the bold coloring back. Pinch the stretched, leggy stems back above a leaf node to encourage bushier, more compact growth as the new leaves come in vivid again.
