Hi,

I planted leaf lettuce in 72-cell tray on March 7. They were inside under the lights for 12 days, then I moved them to the coldframe. For the last week they've been mostly outside. The last couple of days have been extremely windy, so I've made sure they always have water in the bottom tray so they don't dry out. I've tried to shelter them as much as possible from the wind.

Today I noticed the leaves are beginning to turn yellow. Have they been in the tray too long? Do they need fertilizer/nitrogen? I'd already have them in the ground by now, but the beds aren't quite ready. Maybe too much water??? I don't really ever let them dry out and always keep water in the bottom tray.

Thanks for any input!
