Q.impatiens
The leaves on my plants are curling up. Is it too much water or not enough? HELP, PLEASE!

Curling or distorting of leaves is most likely a pest issue.
You can treat your plants with Neem Oil.
It can also be caused by herbicides, was the area near your plants sprayed for weeds?
Here are links with more information.
