Chili pepper just got checked.
This looks like normal healthy growth, not a disease or deficiency. The plant has good leaf color, sturdy stems, and actively developing peppers. Based on the photo and your note, the bottom jalapeño is most likely still filling out and can continue enlarging before harvest if the plant keeps getting enough light, water, and nutrients.
No treatment needed right now
Let the plant keep growing unless you want to harvest for size or flavor. If the fruit is firm and still enlarging, waiting is reasonable.
Also possible, but less likely
What would prove it
Decide whether to wait or pick
If the pepper is still firm and slowly getting larger, leave it on. If growth has stalled and it feels fully filled out, you can harvest anytime.
