I live in Seattle, WA and I water my birds of paradise once or twice a week depending on the weather and it has a well draining soil with drainage in the bottom.
It started getting sick inside and it started with slowed growth and yellow dots on leaves. I thought problem might be lack of sun/watering so I put it outside on the balcony where it gets 2 hours of direct morning light and many hours of indirect bright light.
I checked the roots and they seem very healthy with new bright white growth.
The new baby leaf just looks devastating with every problem you can name 😭
