Although Sun impatiens (“SunPatiens”) are better suited for areas with more sun, they are not immune to sun damage. It’s possible that yours are in too sunny of a spot, so transplanting to an area that gets part sun might help them out. Alternatively, yellow or whitish leaves can be cause by over- or underwatering. Are yours in a particularly wet or dry spot? This could also be the cause of your off-color leaves and blooms.
