Help with young plant to move under 600 HPS

Hi there everyone, this is my first grow, and i need some simple questions answerd.1. i have some young plants, about 2 weeks old, i was wondering when can i put them under my 600 watt hps light, some off them are really small and some have taken off really well, 2. when can i start giving them nutrients.

I would suggest 3 weeks keep the watts to 100 at this time can i see some pictures of them to see what they look like or how big they are

they would be fine now.... once they get passed seedling growth you can move them under HID lighting...

Start them at a good distance away from the light (at least 2 feet)and slowly move them closer as they adjust to it. As for the nutes, depends on your soil. I think most people are feeding by the 4th week. Happy growing.
