1st Time Grow and Need Help Pls.

I need help. I did not expect the to crack and grow so fast, so for the first 3 days they really did not have a good light source which caused them to stretch. They are now well sadly LOOK! It has not even been a week yet but the have a good root system.

1. Can I put them into the EBB tonight?
2. The water temp is 68 is that to cold?
3. The lights out time is in 4 hours should set it to water tonight?
4. I can not remember how often I should water them. Is it 5 times a day for 15 mins?

I am so many more questions and really glad for this forum.

TIA

OK well I put them in the tent on 1/29/12 and start to use nutrients on 2/1/12. The pictures above are what they looked like on the 29th and these are 7 days later. I was so worried about them, but as you can see they look good. right? They look a little yellow instead of the dark green they where.



These cracked on wed night. I wanted to put them in on sunday but my I was sick, so they are running 9 days behind the others. 2 Sour Cream, 2 Cataract Kush, and 1 New York City Diesel. I might have bit off more then I can chew because I will have 9 plants in the tent. I started on with half the amount of nutrients and I thought I would keep it there until I start to flower them.

How long should I veg them before switching over to flower? I have a 2x5x5 tent with a 600w light and a flood/dump hydro. I wish it was a 6ft tent BUT... I'll post more next week. Oh sorry bout the ! in the subject.
