Hello: I have 2 questions about my Pilea plant. I keep watching it everyday but not sure it is a problem or I am just too worry. Can anyone help or give me suggestion? 1. I noticed there are some white dots on the bottom my Pilea's leaves. They are on the new leaves but not on the old one. Is it normal or it is some kind of diseases ? Should I cut the leaves away before it spreads out? 2. a few of the big round leaves are turning yellow but the new growth are green. Is my watering schedule ok ? Does it getting enough sunlight ? Any guidance will be appreciated. Thank you!
