What have I done ?

[JimmyWu]

Hi all... I was planning to start a new thread on a Camp garden today. But will have to take care of this little problem while I still have a garden to start.

Here's a pic of my plants less than a month old.

The cotyledons are yellowing and falling off, is that normal ? Also, some of the true leaves have dry patches. Looks like they're dying off.

I've had them outside in the shade a few times, and in a sunny window for short periods. I water with a sprayer when the the soil looks dry. I did have my daughter water this past weekend while I was at work, she may have over done it.

I keep them under lights ( T8bulbs ) 1-2", for about 12-14 hrs.

Are they to wet and maybe getting a little burned ? I'm also using Ferry Morse starting mix.
