I have a fiddle leaf fig for 3 weeks. The leaves on top have no spots and look healthy.. but on the underside of the leaf there is brown spots.. is that normal or an I doing something wrong? I'm not sure if it is was like this before..

That's normal. It is good that you have it double-potted. Keep it close to and in front of a sunny window as Fiddle-leafed Figs need lots of indoor sunlight. Water it as soon as the top surface of the soil feels dry.

Thank you so much!
