Hello! I’m new to plants so any tips would be greatly appreciated! My begonia has been losing a lot of color and the leaves have been turning brown on the edges. The flowers are also losing color and I’ve had to cut a lot off. I’ve only had it for 5 days and it came with some brown leafs that I’ve cut off but more have been discoloring. Does anyone know what the problem could be and how to fix it? Ive watered it twice so far and put it next to a window because it’s partial sunlight. Thank you!
