What is happening to seedlings?

Water when lights are on. If you spray the plants, do it at lights out..

Correction wedding glue; "cotyledons" are pointing upwars. I wrote 'leaves'

To avoid helmet head make sure to plant your seeds with the pointy end up. Where the tap root exists the seed is the point end. If you start in water make sure the tap root is pointed upwards when you plant it. It will do a uturn and head down into the soil while the seed pushes up. The soil will force the seed head off if you plant it correctly by the time she hits the surface.

I watered monday with a spray. Not much, just around the plant so the roots wouldn't suffocate. Top inch of the White Widow and Wedding Glue seems to be dry already. Should I water during lights on? Or shall I do this after lights go off? One leaf of the gorilla cookies had the membrane so I took it off with a tweezer. That is why it is smaller but the bigger leaf seems to lost it's stripes at the top? Or is this also a normal thing?
