Beginner Gardening: Over fertilized!, 1 by masciam

Hi,
I couldn't figure what forum I should use to ask this question, so I'm posting here.
I have 4 small (12 inches) window boxes in a shady window, with commom impatiens and some summer wave Torenias. Last week I fertilized them with 4-14-8 at half the recommended rate, and now the torenias seem to be burned by it.
Most of the new leaves are turning brown and curling as you can see on the picture.

Is there anything I can do? I've been watering them with lots of water, but I don't know if that makes any difference.

And will they recover, eventually? The plants still look good and I don't want to loose them!

Thanks
