Too much sun or a feeding gap

What's happening

Moon Valley Pilea grows on the shaded forest floor and isn't built for strong rays. New leaves bleaching to a pale, washed-out yellow on the window side points to too much direct sun scorching tender growth. Pale, weak new leaves with no recent feeding instead point to a nutrient shortfall, since young growth shows hunger first.

How to fix it

Move the plant out of any direct sun into the bright, indirect light it prefers. If feeding is overdue, start a balanced liquid fertilizer at half strength through the growing season. New leaves that emerge after the change should come in a healthy, textured green.

This is general guidance based on common symptoms; individual plants vary.
