Leggy brassica plants

My plugs I purchased I potted on to beef up and to provide time to finish the bed they have gone a bit leggy will plant out over course of next week, will I get away with planting deeper up to say first leaves on the broccoli, cabbage and cauliflower ? See picture advise would be great thanks on this wet Saturday!

Up to say te first leaf? Wht about one te binding I gess thy would grow straight once out ?

Thanks MOS
