seedlings bounce back??

Can a seedling bounce back? I got 2 plants on day 8, 18/6.. I overwatered and added extra nutes.. they started curling, started tan spots, one of the cotyledons on both plants are tanish, dry-withered looking.. to counteract the measure I took, I cut off the bottom of the cups they're growing in, exposing the soil.. and I flushed the soil with water, 1x a day, the water drips out from the bottom.. They stopped curling, but the coloring still continues, and their leaves are lookin messed up.. I'll post pics soon, can anyone help?? anyone kno whats going on?:confused:

It sounds like you are still over watering...
