yellow sprouts ...?

Ok so I got some seeds germinated, they were about .5-.75 long when I planted them yesterday. I put them under my t8's with a covering on them until they were to sprout above the dirt . I checked today and 3 have sprouted about .5 above the soil but are all yellow. Should I be concerned???? A little worried ...

Anyone have this before???

we need details. what type of soil your using, temps, humidity. and are you using any nutes cause thats a big no-no for seedlings.

At this stage...just give it time.

They just want light to get their photosynthesis cookin.

Yep must have been the light, they are green and looking straight up now! Never had yellow babies before haha
