If your plants come back to life, dig them up, cut the first two leave off and re-plant them to just below the top of the terminal bud. You have way to much stem for that small of a plant. This can only be caused by insufficient light during initial germination and/or over fertilizing.
Bury the stalk and it will generate new root growth, reduce evaporation through the leaves and create a stronger stalk after it/they become re-established.
Don't add any fertilizer for a couple of weeks.
Water to keep moist, but not wet for the first few days, then allow the soil to dry and toughen-up the plants. After the plants have wilted from lack of water, water them thoroughly and let them dry out again. You should be able to go a week before they need water again.
Plants will wilt during the heat of the day and rise from the dead at night. Your plants should look plump and healthy in the morning and like they're dead at 5:00 in the evening.
