First Grow - Closets, 400w & 600w MH/HPS COME ON IN I NEED ALL THE HELP I CAN GET!!!

Sup RIU. Name's Kronik and this is my first grow/grow journal.

I've been reading around these and other forums, gathering knowledge and asking questions for the past month or two, and I think I'm finally ready to begin. I have already ordered and received my 10 feminized Northern Lights seeds from Nirvana (amazing service btw - 4 days! ) and just started three on their germ about an hour ago - hence the post. The seeds shouldn't pop for a day or two, so in the mean time I'm gonna start up this journal just so I won't have to later. Normally I wouldn't like to be so public about my growing (don't worry, I'm medical), but I've decided to do this simply because it's my first god damn grow, and for all the research I've done - I'm still going to need a lot of help. There are too many specific questions to be asked and answered, and too much of a wealth of knowledge in the combined intellects of experienced, well-yielding growers for me to know everything I need to know right now. Also, I need some place to organize thoughts - my own and those of others - and I feel this would be the very best place to do that.

So it begins.

Set up
I don't have just one grow closet, but two. And both are in different locations. I did this simply because I don't have enough room at my house, and I have another friend who's also a med patient that I can trust not to steal my plants, provided I give him proper medical reimbursement. And yes, there will be differences between the two grows simply due to a difference in spacing. His closet is smaller than mine, so I will be using a 600w in mine and a 400w in his. The dimensions of my closet (that I am working with) are 3.5'x22"x6'. I know - dinky, lame, whatever. Shut up. It's all I have right now. I do, however, have a question though about this - even though a 600w is to be used in a 3.5'-4'x3.5'-4' area, can I still maximize the lighting to its full (or at least close to it's full) potential in the area I have? I will be growing between 4 and 6 plants in my closet, and 3 in his (the 3 currently germing are being germed for that purpose). Overall I'm looking to yield 12z's to a pound - tell me if this is unrealistic, because at .5g/watt I really don't think it is. I've taken into account the limited space and the most likely catastrophically shitty mistakes I will be making as an amateur. Also, another thing to point out that is important is as of right now we are just starting at my friend's place, not mine. I will be starting in a few weeks at my house and I will give you guys an update when that happens. So, just to put everything in perspective and show you what I'm working with, here's the list:

Lighting
1x 400w magnetic switchable ballast
1x 600w magnetic switchable ballast
1x 400w HPS bulb
1x 400w MH bulb
1x 600w HPS bulb
1x 600w MH bulb

Also important to note is I am using MAGNETIC ballasts, without air-cooled hoods. I'm definitely expecting to see them kick the heat up so I'm interested to see just how hot it'll get. I asked the dude at the hydro shop about this and I was told as long as the house is air conditioned and the door is open (more than just a crack) I should be fine on temperature. Let me know your thoughts on this. I'm going to try and keep the AC down to 76-78 but it can sometimes get as hot as 82. I've heard NL is a very temperature-resilient strain, but I'm still a lil bit worried about this. I know that lights gonna increase temps by at least 5 degrees.

Nutes
Fox Farm Grow Big
Fox Farm Big Bloom
Fox Farm Tiger Bloom
CALMAG (will buy a bit later on)

Just wanted to get the trio for now because, hell, it's all I can really afford. The solubles are expensive, man.

Soil
Fox Farm Ocean Forest
Perlite

These will be mixed half and half. I really don't want to shove anything else in there like peat moss, guano worm casings, coco etc. It's simply too much of a hassle and I really don't want to "try anything" right now if you know what I'm saying. I'm not looking to experiment with different mediums. I'm just looking to get through my first grow. Other methods and mediums will be tried later but for now I just want a simple and effective medium that is tried and true and will get the job done.

Few Questions About Germination
I did the paper towel method (2 under, 2 over the seeds) in a semi-deep plate wrapped in saran wrap and placed it in a cabinet in a room where it stays relatively cool, but not necessarily cold. I'm kind of worried with this method, though, because I'm not sure when to open the saran to give the seeds a breather and how often I need to do that. And considering I started them in the late afternoon, I will have to leave them in there overnight. Any advice on this? Will they be fine in there on their own? Idk just stressing I don't want seeds to not pop I gotta make every one of these count.

Anyway that's my general introduction. Can't wait to get goin with this grow.

Peace.

DAY 7 (Day 4 for the other 7)

Seedlings are looking great. Now I can't really do pics cuz my cell phone pics fucking SUCK but I'll try and get iphone pics later if I can borrow a friend's. However, I do have one pic for you guys. Yes it is a blurry, shitty cell phone pic, but it's important because it shows a concern I have with the seedlings. Their cotyledons (the rounded leaves that first show up along with a set of sharper-looking leaves at the beginning of veg) are folded up on some of the plants. I think about 5 or 6 (don't have em in front of me right now) don't have this problem, but a good 3 or 4 do and I'm kind of worried. I've tried googling but nothing came up except "curled fan leaves" which is not my problem. I dont think its a nute deficiency, its just growing weirdness. Also, since the cotyledons are still folded up, some of the plants are trying to grow through them but not breaking through the fold and as such, their new set of leaves is getting scrunched under the folded cotyledons. This is seriously worrying me because idk if this is supposed to happen in some plants or if it's normal and the leaves will eventually break through the fold and the cotyledons will eventually fold out like the others. Anyway I know this is sort of hard to picture the way I'm saying it so Ima attach a pic. Tell me what you guys think I'm about to do the first feeding and don't want any problems so this is important!

EDIT: pic kinda sucks so I'll explain. What is within the circle are the folded up cotyledons, which should be folded out, giving the plant four of its first leaves, total. However, you can only see two blade leaves, because the cotyledons are attached together (I don't know with what, it looks brown). Could it possibly with something from the seed? Anyway, what is inside that ball is a NEW set of leaves trying to get through but they cant and as such have been scrunched into a ball within the folded cotyledons!

Should I just manually break open the cotyledons at this point. I feel like the plant isnt going to be able to break through this itself it's too delicate! However I have heard people say "just let the plant grow itself. The least human interference the better." But sometimes human interference is necessary - flushing, feeding, topping, etc. I'm trying to figure out IF this is one of those times where I need to step in or if the plant is fine doing its own thing.

Thanks!
