Beginner Gardening: Impatiens Sodenii Leaf Problem, 1 by LemonPeel

LemonPeel wrote:
I have a small impatiens sodenii in a pot. It was transplanted from a yard a few weeks back. After some intial leaf drop it seemed to be doing OK. But recently many of the new and remaining leaves are developing spots and brown tips and edges. The soil is well drained and the location gets morning sun only. I don't see any obvious signs of infestation (spider mites etc). Any thoughts as what the problem might be?

Thanks for any insights.
