We can't help you unless you give us more information about your grow...... copy and paste the section in the sick plants guide here and answer the questions in the soil section and post them here so we can help.
For one thing your plants are badly overwatered...... you water too much or too often and I am sure the yellowing has something to do with the overwatering since overwatering and nitrogen issues go hand in hand.... but fill out the section so others can help as well.

What? I actually have to put forth effort?? What's wrong with you, I thought ya'll were psychic. 
Sorry about that. I have a problem with common sense. O.k., here goes:
How long has this problem been going on?
Less than a week.
What STRAIN are you growing?
Northern Lights
What was the establishing technique? (seed or clone?)
From seed.
What is the age of your plants?
2 1/2 weeks
How long have they been in the soil mixture they are in now?
2 1/2 weeks.
How Tall are the plants?
A little over four inches tall
What PHASE (seedling, vegetative or flower) are the plants in?
Early Vegging
What Technique are you using? (SOG, SCROG etc)
Neither, but I plan on LST'ing when they get big enough.
What size pots are you using? (Include how many subjects to pot)
They're in plastic beer cups.
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?)
Ferti-lome ready-to-use ultimate potting mix.
What Nutrient's are you using?
Ferti-lome soluble tomato and vegetable food 7-22-8
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful*
1/2 tsp. per gallon.
How often are you feeding?
Just once
What is the TDS/EC/PPM of your nutrients used?
¿Que?
What is the pH of the "RUN-OFF"?
6.5 to 6.8
What method of pH test was administered? Using Strips? pH pen?
ph pen
How often are you watering?
That's subjective. I wait until I see the leaves start to droop. Usually 4 to 5 days.
When was your last feeding and how often are you feeding?
Two days ago and it was the first time.
What size bulb are you using?
Using 4 100w CFL's for now. I will move them under 3 150w HPS lights next week along with the CFL's.
What is the distance to the canopy?
About six inches.
What is your RH Factor? (Relative Humidity)
20 to 40% I'm in the desert southwest.
What is the canopy temperature?
68 to 72°F - 20 to 22°C
What is the Day/Night Temp? (Include fluctuation range)
see above
What is the current Air Flow? (cfm etc.)
vortex fan
Is the fan blowing directly at plants?
It's an oscillating fan. So, yes and no.
Is the grow substrate constantly wet or moist?
That would be a no
Is your water HARD or SOFT?
Hard. Straight from the tap.
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water?
Tap water that I let sit 24 hours before using to get the chlorine out.
Are you using water from a water softener?
Absolutely not.
Has plant been recently pruned, cloned or pinched?
Niope. they're just starting out. I'm being gentle.
Have any pest chemicals been used? If so what and when?
No. I don't use any kind of pesticides or harmful chemicals that can leech into the ecosystem.
Are plant's infected with pest's?
Nope. Never had them and I check frequently.
The truly bizarre aspect of this problem is the fact that the bagseed plants are thriving. Not a sign of damage or distress. It's just the Northern Lights.
I hope this helps.

Couple of issues that could possibly be affecting things.
I agree with Stitch that they look over-watered. However, you indicated you were waiting a while so I'm thinking it may be that they are choked for oxygen down below. It doesn't look like there's much drainage/perlite in that soil mixture. Is that the case? Also, what kind of holes do you have in the bottom of the beer cups?
Also: you said that you let the water sit out for 24 hours for chlorine. Are you sure your municipal supply only has free chlorine in it? Many cities use chloramine in addition to, or replacement of, regular chlorine. This cannot be evaporated out of the water.
Last, the food that you are feeding them seems a bit unbalanced for this stage of the game. At least, that's what I would say from the N-P-K of 7-22-8. That's a bit heavy in the P department this early. P and K are for flowering development. For vegetative development, you want something more balanced or with more of a N-oriented formula. Not too hot, otherwise you'll burn them.
That aside though: you said they're only 2 weeks old and they look to only be on their 3rd or 4th set of true leaves. If you are feeding them: you should only be giving them 1/4 - 1/2 dose from what it says on the bottle. But again, I would see if you might be able to find a more suitable vegetative food for this point of the game.
Anyway, that's probably more information than you needed. But, if you can answer the questions that I asked, that would help (at least me and maybe others) out to find a cure for what's happening.
Good luck in your travels!

There are five holes. Four at cardinal points and one in the center. It has plenty of perlite mixed in. In fact the Sativa from hell with my first grow used the exact methods I'm using now and I never had a single issue.
Quazi said:
Once again, same method as last time and no issues. But according to the water authority they don't use chloramine here. Too easy to get into the water table.

What you recommend? I'm all ears.

I'm switching immediately.
Quazi said:
Thank you so much. The information was very helpful.
But, don't you think's unusual that the bagseed wasn't stricken as well?
In my opinion I would not yet transplant them, with them already being stressed and with them being overwatered, I highly doubt they are rootbound, overwatered plants root systems are much smaller than a normal plant at the same age due to lack of oxygen slowing down the growth of the root system I would wait to transplant them until they get a little bigger and fully recover from overwatering.
There could be a lot of reasons for that, particularly as the bagseed is an 'unknown' variety, but the most obvious one is that the non-bagseed plants are simply larger more developed plants. Larger plants will therefore need and consume more nutrients from the soil than the smaller ones and will therefore show any potential problems earlier than your bag seed ones. Don't think that because only one particular strain is showing problems that the others won't in time - they probably will.Totah Sam said:
Your plants are showing signs of over-watering and water-logged soil by their general 'droopy' appearance. This is due to the lack of oxygen in the rootzone caused by 1) allowing all the dissolved oxygen to dissolve out of the water by letting it stand and 2) because the soil has probably compacted and 3) because there's probably inadequate drainage in those home made pots.
Your leaves are showing classic Magnesium (Mg) deficiency problems which is a direct result of the cold, waterlogged, compacted soil.
If those were my plants I'd have them out of those pots and into some proper 1/2 gallon (2-3L) plant pots with correct drainage holes, don't skimp on this it's just not worth it, good plant pots are very cheap. I'm not familiar with your potting soil, but I'm assuming it's an established brand thats sold sterilised and for container plants (plants grown in pots).
Reconsistute the soil before you put it in the pots. By this I mean, measure out how much you're going to need and put it in a container, then work through it with your hands breaking up large lumps and removing sticks, twigs, half composted wood and stones etc, anything that is going to remove from the nutrient content of the soil. You should be left with a light fluffy soil with no large lumps or stones, twigs etc.
Measure out sufficient quantity to fill all your pots and only put one small handful of perlite in and mix it in thoroughly, then start filling your pots. Do not compact the soil down, simply bang the pot on a firm surface to settle the soil. This is ALL the perlite you need, you do not need huge quantities of perlite, all it does is remove nutrients from the soil.
Now you need to understand how to water your plants correctly, look through my posts and you'll find a thread where I've explained the 'wet/dry' method of watering.
Stop feeding your plants in vegetative growth. You don't need to if you've followed my instructions here on soil preparation and use my directions on correct plant watering, as there will be sufficient nutrients within the soil to support at least 3-4 weeks of reasonable growth.
Use the correct sized pots for the correct growth stage, prepare your soil to maximise good drainage and maximum soil nutrient retention and water them correctly = no more problems in vegetative growth.

Thank you for the wonderful advice and insight.
Turns out the girls were SERIOUSLY root bound.
The roots were circling the bottom of the cups.
I'm a bad bad man.
I now have them in 3 gallon grow bags and have the 5 gallon bags waiting in the wings for the next transplant.
I found out from my bagseed source that the smaller ones are a kush variety but not sure which. Just like the pure sativa he gave me last time and assured me they were an indica/sativa mix. I just hope the little frankensteins don't take over my grow area.

Roots circling the bottom of the cups does not indicate it being root-bound. In fact, the roots can circle in the bottom of the cups many times over before growing larger and heading upward. Even then, it's not necessarily considered "root-bound."
If it were really root-bound, then you would not be reporting the roots were "circling the bottom of the cups." You might be reporting that the roots were coming through the bottom of the cups, that the roots were spiraling upward alongside (and almost to the surface if root-bound), or possibly that there were roots growing on the surface.
I would heed the advice given by the very knowledgeable people who have graced your thread in regards to some of the other aspects of your grow.
Just because something works for one strain, does not mean it will work for another.
Good luck in your travels!
