About 1/3 of my Impatiens in my window box are wilting, going yellow and have whitish-grey, powdery looking ends on the leaves. Help!

Likely a Powdery Mildew issue.
Trim away the effected plant material.
Also check watering, make sure the soil is damp but not soggy. Soggy roots can cause yellowing leaves and root rot.
