Help me Obi-Wan Kenobi, you’re my only hope.

These seedlings germinated great. I’m using COCO COIR as a medium. Watering with distilled water using a spray bottle on mist. They got really leggy quick so I added a little more soil to support them and also added an LED lamp. I wait until the soil looks dry between waterings, but I may still be over watering. Two of the seedlings seem healthier than the rest but still are not growing much. These are about a week out of the soil. The stalk at the soil is very thin on most of them. So my question(s) is, are these salvageable, should I add nutrients, what nutrients, how much, how often?

they should pull through not sure why they are on there side.. give them 24 hours bright light for a few days see if they pull through. they don't need nutrients yet but a mild dose of something like rhizotonic wont hurt either.

They don't need feed till they get some real leaves not just the 2 baby ones.. if your in coco just keep it moist try not to let it dry out as its not soil.. don't leave it stood in water and you should be good.

Is the misting actually getting enough water to the roots? overwatering isn't a big issue in coco. In fact it should never be dry, and you want to be watering till you get run off!

Agreed for sure you don't need nutes at this stage.
