At 2 weeks they might be sexually mature and 4days would probably enough to trigger the flowering.
They start growing that single hair on both sides of the nodes when they are "mature" and ready to start producing flowers.

Can't you just leave the lamp on 24/7 or put a timer on it?

They wont go into their bloom cycle until they are sexualy mature. That normaly takes a minimum of 3 weeks from sprout. I think you will be ok. Worst case they are a day into bloom and you can switch them back before any real flower development and can easily be reverted to veg growth with a few days at 18hr light.
