Did you harden them off or just pop them into the cold frame? If not
hardened they can show yellowing from differences of temp, light or
they could merely be over-watered. You've got plenty of time to start
new ones.

Just put them out there , no hardening off . Not likely they've been
overwatered , I'm careful to only water when the soil is dry a half inch
down . I think they'll make it , I really wanted to get a head start this
year . Last year the seedlings were puny and weak ... I guess going from a
uniform 70°-80° temp environment to night time lows in the 40's is the cause
. They're still sturdy and not showing any real signs of distress other than
a slight yellowing of (mainly) the lower leaves . Everything else seems to
be doing well . They for sure get better light out there than they did
inside , one window 3' wide and nobody got more than a half-days sun . The
grow light helped , but still , there's nothing quite like real sunlight ..
Thanks Steve !

No problem, they'll most likely grow out of whatever their problem might be..
