White film on sprouts.

[Flip Flop Tan Lines]

Hello.....I am new to the forums as well. Sounds like air circulation and too much moisture to me. I placed a fan on my seedlings when this happened and seemed to help alot.....good luck =)

Water only when dry, the air circulation Flip Flop mentioned is crucial...
Dust the soil under the seedlings with powdered cinnamon, yes cinnamon, it will ward off bacterial attack, and DAMP OFF disease...

we dust the soil under our sprouts every year, over 1500 of them...have never lost any with these measures...
but without the cinnamon, circulation and moderate watering...in the basement it's cool, damp, under the lights...the sprouts die !!
