And if you just switched them over I wouldn't jump the gun thinking something's wrong with them. Best way to tell if it's N def is if the older leaves at the bottom are turning yellow. You just flipped them which means they're not flowering yet so it's ok to keep giving them nitrogen.

As said without pics it is hard to say what is going on. Sounds like you aren't feeding enough N but without pics who knows.
Also you don't wanna switch to flowering nutes until after the stretch. Usually around week 3-4 from flip with most strains.

Cheers
