Nitrogen defficency? google it.

Or maybe an iron /pH issue.
Or any number of other things that nobody can determine because there are not enough details about your plants environment. Your not off to a shining start for your very first post. More details and more pics please. The ones you posted were great but it would be great to be able to see the stems also. Are they red? Whats your soil? Where does your water come from? Do you have a pH meter and if so what is your pH?
The more details you offer the easier it is for people to offer a realistic opinion. I, like a lot of people here, would love to help but you're making it harder by being not offering those details. Did you read the marijuana-plant-problems section yet? If not then give it a try......

thanks for posting more pics and the info.
which miracle grow soil are you using? does it have time release nutrients?
what is your feeding/watering schedule like? are you letting your tap water sit out for 24-48 hours before using it?
did the yellowing just start suddenly?

I agree, its not a nitrogen deficiency... here check this out http://www.greenmanspage.com/guides/plant_abuse.html
1.I use potting mix (it has Nutes already in the soil dont know if time release)
2.my 1st week of flowering i using just flowering nutes now im in my second week i mix it with the veg+flowering nutes together and water them this week it started getting more yellow two days after that i flush it with ph water of 6.6 and now im at this point here
3.no i dont let the tap water sit out for 24 to 48hrs
4.the yellow has been going on for bout a week and its getting worst i dont know what to do

I know you said you flushed once already but you used water that had chlorine in it right?
take about 15 gallons of tap water per pot and let it sit out for two days. if you have an air stone bubbler then feel free to use it, it will speed up the process of chlorine evaporating from your h2o. you could also just buy some R/O h20 from your local grocer and use it instead of waiting the two days.
when you have pHed chlorine free h2o at room temp then flush each pot with at least 3 times the volume of water that your pot holds. so a 5 gallon soil pot gets flushed with 15 gallons of h2o. I do this slowly in the bathtub.....I also let the plant rest a few minutes between each 5 gallons.
So what is your nutrient feeding schedule? Do you feed every two or three waterings? Are you following the directions on the label of your nutrients?

most people will water twice, then feed. or feed every other watering. the feeding/watering should only be done when the soil is dry up to your second knuckle when poking your finger into it. i have never used the nutrients that you have but your soil already has time released nutes in it and you may be suffering from lock out. flush like i mentioned before and slow down with the nutrients. it may take a week or more before things straighten up.

One thing to keep in mind is that the time release fertilizer in MG potting soil works by being watered, the "time release" is contingent on waterings, the more you water the more the time release fertilizer's shell/coating is deteriorated/dissolved and eventually breaks and releses the nutrients. I know some other brands of time release fertilizers work differently such as being contingent on temps etc... so correct me if i'm wrong that MG time release doesnt work this way.
As for the discoloration, I would put my money on an Fe/iron deficiancy. And as to what to do about it???? thats a tough one because it could very well be that the MG time release ferts arent working well with the additional nutes youve been watering in? Hopefully it is just a ph or nutrient salt build up that has locked out other nutrients!
Either way at this point all I can think of doing is flushing and making sure your ph is in fact correct (test run off) and maybe get a bottle of micro/secondary nutrients and use at half strength, I can almost garuntee that your problem is not any primary nutrients such as nitrogen. Also I would not use any additional nutrients in that soil unless you start to see a deficiancy of any primary nutrients NPK, with time release ferts you should only have to feed additional nutrients if the plants needs them, watering in extra nutrients is probably only going to interfere with what the time release is made to do.
Moral of the story is: dont use potting soil that has time release fertilizer in it! oh and you should be de-chlorinating your tap water.
Foliar feeding with a micronutrient product a couple of times should speed things up a bit, do not foliar feed directly before or after watering/flushing as your plants will suffocate, and it wont hurt to rinse them with a misting in between foliar feedings.
hope I didnt mess ya all up with all of that, if you have any Q's I'll be around. Goodluck!

oops...I just realized that I jumped the gun a bit early and assumed your Miracle Grow soil had time release nutrients but you didn't specify which MG soil you had. I have used their Organic Choice Soil before and I know that it does not have any time release nutes at all but my pH would swing drastically a few months into it. If you must use MG soil then be certain to supplement it with dolomite lime or garden lime.
I still believe its an iron or magnesium deficiency either due to excess amounts of Phosphorus or from your soil pH being unstable.

I disagree.
How is 3 times the soil volume an excessive flush?
Yes, anytime you flush or add water more nutrient is made available to your plants but you are missing the obvious part of flushing...the part part where the baddies get flushed.

If yer light is HPS and too clsoe it will belach out the leaves... mine diod that on a few plants, i just moved thenm out of the hot spots and they returned to green no nutes added
