What to do after overfeeding and a flush?

Wait to water or feed until you can stick your finger into the soil and it feels completely dry. It may be too saturated with water at the moment and can't get any oxygen with it's roots. Plants need oxygen to stay alive, contrary to popular belief. Once it dries out, do what grannie said. Give it some nutes at half strength, let it dry out again, give it normal pH'ed water, let it dry out, Then you can start feeding her properly again. But, don't forget, you don't want to feed two waterings in a row. Stick to a feed -> water -> feed -> water regimen unless your plant tells you it needs more food.
