Second Grow! Northern Lights & Snow White...

Hello people, I have started my second grow but its a bit more advanced than my first...

I will be growing Nirvana Northern Lights & Snow White in a Secret Jardin DRS100. I have a 400w HPS. I also have Canna Terra nutes and plenty of pots lol

Basically the Snow White are looking pretty good. The pictures show 2 weeks from when I started germinating the seeds, they look good but when should I start using the nutes?

The NL seeds turned up later and therefore havent really finished the germinating stage yet. I am still waiting for most of them to break through the soil...

Also I have the light on 24/0. I am only doing this as I accidentally blew my MH bulb and had I not have done this the plants would be getting 18/6 via a 400w MH. Which is better 24/0 HPS or 18/6 MH for Veg?

Forgot to mention, the tent is in a cold room and temperature during day time with the light on is 74F is this okay?

Thanks, Joe. :bigjoint:
