Problems on 4x8 flood table

[Frazzled]

Hi,
When I put small rooted (4" rockwool) plants on a 4x 8 flood table they turn a dark green sickly color. The roots grow good but not the tops. They wilt and look unhappy. After 2 weeks they come around.

Using GH at 500ppm w/2x1000 mh.

ANy suggestions on the best way to transition from 400w to the table?


Thanks in advance.
