How does it look?

Very nice!! I don't see any pre-flowers yet, but I hope it's a female. I want to see you finish this

 

looks good..i think you might have mites though bro. I think those little white dots look like mite damage.

 

Oh no! Get rid of them! :O

edit: question, does your plant smell at this point?

 

i believe the bugs themselves hang out on the underside of the leaves. flip 'em over and see if anything is moving around.

 

I have spent nothing on my grow also and ive got a beautiful 2 foot bushy plant myself gota let the hater hate

 

Yep they call it weed for a reason. However I think most people like to hate because you could have doubled/tripled your yield by using a good soil mix with nuts, topping and lst'ing but it does feel good not having to babysit plants.

 

She has spider mites obviously First thing first get rid of em..those white spots are perfect em apples of the damage they do hen they suck the frikkin leaf or whatever

That actually would be the perfect example of spider mite damage, you NEED to deal with that they will kill that plant left unchecked.
Also did you remove any growth, usually a plant left to grow from seed will grow branches, not usually always.

 

I'm sorry disregard the branch statement, how young is she how much direct sunlight does she get?

 

I agree with Numbnutts & everyone else - spider mite damage, get rid of the little bastards ASAP!!!!
I could give you any number of suggestions on getting rid of the spider mites as long as you're not hellbent on staying the zero dollar route - like Azamax or NEEM oil or Spinosad or MightyWash.
Not criticizing your zero dollar thought, kinda cool actually, but.... say you went to the health food store or vitamin shop and bought a $6 8oz. bottle of Dr. Bronner's Magic Soap, in the Hemp Lavender or Hemp Peppermint scent. This is not for your plant, it's for your girlfriend. Now, let's say you accidentally put 1/2 tbsp of this in a quart spray bottle and accidentally fill it with water and shake it up really well. Then just after sundown you accidentally spray this on the entire plant, especially on the undersides of the leaves. Then, since it was so much fun using your girlfriend's soap, you accidentally do this again every 4-5 days for at least two weeks (wouldn't hurt to do longer). Chances are the spider mites would be gone, and it would all be accidental and you still wouldn't have spent any money on the plant, and your girlfriend would think "how thoughtful".
Then she buys you a 400W HPS setup for your birthday and INSISTS you bring that pretty little plant that smells like her soap, inside.
Gotta love it when a plan comes together.......

 

Better a spider mite problem now than later when the plant is more complicated structurally (or worse, messing up bud).

I spray a solution of neem oil (as Olde School mentioned) and cover anything I grow right before the lights go out. probably don't want to do it during the day as a beaded-up solution could probably cause it to water burn the leaves. You'll be spending a little money (very little) but it's organic, food safe, and at least in my experience it works very well. After a few applications they were gone, I still use it as a preventative measure.

 

$0 solution: spray it with your hose, if you have a handle with a selector use "flat" or "shower", get under the leaves to knock them off. Some people use their shower head if it's on a hose, right in the tub.

 

I was kinda hoping you'd go the route of getting your girlfriend to INSIST you bring that pretty little plant inside that smells like her soap!!!
But the neem oil is A#1 recommended, because it works and is totally safe. Just get them under control before it blooms.
Besta luck to ya!
