400 Watts HPS From Seed-Bud..First Grow! THCB + Mazar + ??..Its Official

This is my first grow, and to tell the truth I didn't even plan to grow when first arriving on this site. Now this is all I think about. I've gained a lot of knowledge that I was a complete noob to..Still am but learning.

This is my first grow and I have put quite a bit of $$ into it.

I've been posting bits and pieces of my grow, asking questions, and requesting advice. I figured what the hell, go and get the shit. A couple hundred bucks later + knowledge =

2'8x2'8x5'3 Grow Tent.
6 26 watt cfs
400 watt HPS with cool-tube
4" inline fan 170cfm (exhausting hot air)
4" inline duct fan 80cfm (passive intake)
Fox farm Ocean forest soil
Light warrior for seedlings
Big bloom, Grow big, Tiger bloom
Earth nectar + earth ambrosia
Superthrive
Liquid Karma
Sweet by botanicare

Ok.. To start off I germinated them using the paper towel method.
Placed them in Fox Farms Light Warrior soil in 16oz party cups.
Put 6 26watt 6500 cfls on them for a week..

Today is the 8th day, I took away the cfls and slapped on my hps.
Temps are high. 85F
The intake fan is coming from htg..should be here in 3 days..and I plan to draw the cold/neutral air from the basement.

Ill post pics as they develop I guess, because theres only 1 set of true leaves

Suggestions appreciated

Even though my plants are 9 days old, can I add a SMALL amount of nute..

I was going to use 1 tablespoon of Grow big and big bloom but wondering if i should cut that in 1/4ths or not??

Nothing new except I have taken out all my cfls.

For light I threw my 400 watt HPS on them. They seem to like it so far even though temps are high. 85F.

When I get my fan in a couple of days I wll have an intake so the air will be much cooler.

Other then that im just waiting. How long before the second set of leaves shows up because I want to start adding nutes even though I know your not suppose to?

Also when should I transplant? They are in 16oz party cups.

Wow Ok..So I realized that my roots were all the way at the bottom of the cup so I need to transplant asap.

I have my pots filled with ff ocean forest/light warrior and filled the bottom with mulch.

I will take pics tomorrow when I transplant because I need rainwater (dont want to put tap because of the chlorine, and don't have time to wait 24 hours)
