[Grow] Sharing my adventure into Cannabis

I'll be sharing my adventure into Cannabis, this is my first grow and I'm excited to get going.
I'll be growing 6 different strains with maybe an auto thrown in for good measure.
I'm using a XL tent 4x4x8 and 2 400W lights both HPS/MH.
I'm using 4inch pots to start off seeds, when I see some roots hitting the bottom I'll proceed to transplant into final containers.
I have Jacks Classic 20-20-20 with a lot of additives that I may, or may not, use. Advanced Nutrients B-52, Voodoo Juice, Rhino Skin, Big Bud, Overdrive, and Snow Storm Ultra (Not sure what this really is)

Since this is my first grow, I won't be transplanting to keep everything really simple and fuck up free. I'll be using 3Gal smart pots, I've heard really good things about them and I only intend on my plants final height reaching 3-4Ft.
I'll most likely be vegging 1 1/2 Month, then switch over to 12/12 so I can finish by the summer.
The tent is already set up and I'll have pictures following tomorrow.

I'm very open to advice any experienced growers can give, even though I've read a lot, I can still have a long way to go.

Strains I'm growing:

Purple Wreck - Reserva Pravada
Sage n Sour - TH Seeds
Sharksbreath - DNA Genetics
Silver Kush - Reserva Pravada
Green Crack - Cali Connection
Gigabud - G-13

Strains I might add

Auto White Widow - Dinafem

In this picture we have 3 at 1 week old, 1 at 4 days old and 1 at 24 hours old.

Far right (Sage N Sour), far bottom (Purple Wreck), and far left (Sharksbreath) are 1 week, middle (Silver Kush) is 24 hours old, and far top one (Auto White Widow) is 4 days old.

2 Other seedlings are cracking today (Hopefully)
Which will be Green Crack & Gigabud

Anything with white roots at the bottom of the 4inch pots were transplanted into final containers and so the journal begins.
