yellowing seedlings help needed pls

[CanGroIt]

what should i do just put bricks under the cheese raising the plant to equal height? or keep topping the blue?
They are now under a 600w hps with airwing, and im feeding these lucky ladies with suger peak( the best imo)

I prefer LST over topping....but both work....

Might want to drop that 600 a bit.... Them blueberry look a little stretched, even for a 600... Kid you not, my 1k sits 18" from the tops.... Do the back of hand method to make sure you don't put it too close....
