ok i have on plant in a container that was outdoors and brought it in and it was fine for like 5 days i never watered it once since the soil was already soaked and the other day i gave it a whole lot of sun in the window and the leaves were curling upward turned dark green and i can see blackspots through the stem,also they seem to be developing brown necrotic spots them the leaves are drying up and becoming crispy,this is effecting the entire plant i dont know what to do ,put it back out side and let nature do its thing or try to add ferts ? he
