Got it at a big box store about a week or week and a half ago. Keep it inside near a big window with indirect sunlight. At the time one or two of the leaves were pretty translucent and a dark orange where the rest of the plant was not translucent and more green in color. Now, many/most of the leaves are becoming translucent orange and falling off easily. Some leaves even have dark spots. Don't know if I did something or if it was sick to begin with. Any way to help reverse it?
