tips of leaves yellowing... *whimper*

The tips of my sproutlings leaves are starting to yellow. They are 1 week old today and are just getting their second set of serated leaves. I've got 2 40-watt aquarium fluorescents hanging 2 inches above the sproutlings and they've done well so far. I recently added ventilating because they had been suffocating (but the ventilation was installed 2 days ago and their health was improving, or so it seemed). Any tips? Tips of leaves yellowing? They're a lil droopy? exactly 1 week old? tips?

:stupid:

Pull the lights back. to six inches or so for a few days...what are you growing them in..soil? ph?

probably over-watering ... depleting the available nitrogen ... :smokin:

droopy can be over watering, so i read

get more lights maybe? and let em dry before watering soil

u using plant food?

yea my leaves were yellow for a while i figured out it was too much water. i just didn't water for about 3days and have been watching my water levels its now doing better
