7 days from seed

So many questions. where to begin
I know all my questions answers can be found in other threads. but it means more when people take an interest in my project and take the time to help me. Also I just simply don't have the time to read. I work too much and only have maybe an hour a day, and the weekends to dedicate to my plants..

So my seedlings are 7 days old. (7 seeds- 6 germinated- 5 sprouted)
I have them in a 2'x2'x4.5' tent / under a t5-44 / 24hr / soil
The light is about 10'' away, temp average about 90 and 40% humidity.

1. When should I transplant into a bigger pot
2. When should I start nutes
3. Should I start giving these girls a few hours sleep a day
4. What temp is in the danger zone for these lil gals?
5. What should I be preparing for in the weeks to come!

These are just the facts, I honestly dont know how I'm doing, so let me know!
When these lady's are ready, they will go in a 5x5x6 under a 1000w hps

Please follow my journal and help me along the way, I would be so grateful!

1. When you see roots coming out of the bottom of your pot or the leaves spread wider than the pot.
2. Don't start nutrients and till you see the first set of three-finger leaves or you can wait till they tell you they are hungry. But remember to start off at a quarter strength dose no more than half a strength dose.
3. It's totally up to you if you want to let him sleep I usually let them sleep at least 6 hours I find no difference in running the lights 24 hours as opposed only running the lights 18 hours some people like 20 hours on 4 hours off that's how I did my first grow but really haven't noticed any difference other than electric cost.
4. You're pushing it at 90° they prefer between 70 and 80 degrees it's not going to hurt them as long as you don't exceed triple digits.
5. Be prepared for a wonderful Adventure. It's the coolest thing to watch these little plants grow.
Just remember to let the soil dry out between waterings and if you run into any pest problems any bugs whatsoever take care of them immediately doesn't really matter what they are take care of it right away. Good luck.

You can check out my beginners grow guide at budsgrowguide.com. It will walk you through all the basics.

1) I transplant out of the first pot when the seedlings leaves are 100-150% as wide as the cup. Until the largest leaves reach the pot rim the plant is spending most of its energy building a rootball. Qaiting until the leaves hang over the rim will help kickstart the vegging process.
2) I start half-strength nute water after 10 days in dirt. A week later I give them full strength nute water daily.
3) Plants veg best at 24/0. Means mine don't see any dark until they go to the flower room.
4) I temp check daily when the temp gets to 80 degrees and take action at 85 degrees. Over 85 is worry time.
5) Set up your flowering space. I find I need about 4 times the floor space to flower plants as I need for vegging.

Good luck, BigSteve.
