Also is it possible I introduced them to the MH too soon? They all seemed to have a pretty good root system built up in the Rapid Rooters.

They are approximately 9 days old from when the tap root first broke through the seed. They sat under CFLs for 6 days and friday evening I moved them under the MH.

Was this too premature? I did my entire Veg with CFL's last time so I'm not sure if I'm shocking them with too much light at once. They're under a 400 watt MH right now.
