Thank you the reply floridian! Should he try adding more nitrogen to the plants to correct the error? Or just keep doing what hes doing?

Definitely not at this stage.After 12/12 you may want to give small amounts of nitrogen the first couple weeks or so while the plant is still basically vegging.This helps with yellowing in early flower and assists with the plant stretching.
