Seeds sprouted April 13 and are failing to thrive. Please see photos and help me!

Two Northern Lights in coir. Sprouted on April 13. After the first few days I put in very light nutes, I thought. I have been adding tiny amounts of 6 ph plain water when soil is dry at first knuckle. So frustrated as the seeds weren’t cheap or easy to obtain. Can anyone help me? Thank you so much!

They need nutrients with every watering. Coco coir has no nutrients

And maybe moisture. At this point I'm usually still misting the leaves. Sprouts at this point still want high humidity.

You might also check the temp. With them being right next to a window, depending on what the weather is like, it could be too cool for them. Seedlings, like 90Gizmo mentions, like higher humidity and warm temps. They also don't have roots that are able to take up water, so misting them when you water them is a very important step since they take in more water through their leaves at this stage in their life than their roots...hence seedlings liking warmer, more humid conditions.

Stick a plastic dome over the top of them....I use fruit juice or coke bottles cut in half....give them a water with 10% nutes....and chill
