If they were in fertilised soil I would possibly agree but they aren't, they look to be in coco. Coco is an inert, hydroponic medium, if he was to leave the feeding until 5 nodes they would be dead before they got even close.

Aquanaut, if you are using Canna's coco balance nutrient formula I'd got with about 1ml/L A+B, increasing to 1.5ml/L if they haven't greened back up in the next few days.
