How do I save polka dot plant

Question

I bought polka dot plant 3 months ago from Walmart. It was growing very well for about a month. Once I kept it outside on patio and it started drying out. All the lower leaves turned brown and size is shrinking. I water it every 2 weeks and add miracle grow all purpose food plant. First picture is month old, rest of pictures show current state of the plant.
Please let me know what do I need to do?
Thanks

Watering every 2 weeks is not likely enough. You should check the soil, it should be moist; never soggy and never completely dry.
