I think all the overwatering talk makes first-time growers not water enough! How tall are they? If they are in small cups for containers then you can probably be watering more than every 3-4 days! As they start to get rootbound you can water more and more, like every other day, maybe more.

I was having similar problems. Remember if they're totally dry for a day or two, they're not getting ANY moisture or nutrients! The soil needs to be slightly moist, not wet! If you're in an arid climate you'll have to water slightly more.

When to use nutes depends on what kind of soil/mix you're using. Your plant probably needs them if there weren't a lot in your base mix. If your soil was "hot" you're probably getting right to the point where you might want to hit 'em with a 1/4 or 1/2 strength dose and see how they respond. But if they didn't look like they needed it then maybe I'd hold out.
