Thanks man, that's what I'll do.

I have some seedlings in rock wool, that sprouted about 72 hours ago. I've got the temp set to 77F, and they're under a 600W MH bulb set to 75% power. Humidity in the tent is stable at 40%. I have been giving them pH 5.9 water once a day. Should I be waiting until the top of the cube is dry...

Nute levels look good, just water more frequently. Edit: Also, what is the temp at the canopy? Are you moving air around the plants with fans?

That extreme leaf curling in the first pic is a dead ringer for heat stress/insufficient watering. http://www.growweedeasy.com/heat-light-stress
