Lower leaves are bright yellow!!!

Well my plants have been in veg state under 24 hours of light for 3 weeks already. I really don't know when to set the timer for 18/6. But in another case the first 2 leaves in the bottom are turning a bright yellow. I just transferred my plants into a bigger pot. Im kind of getting worried, I dont want my babies to suddenly die. =( I've attached some pic's so if anyone takes a look they can maybe help me out with my problem and if you need more info about my plants post here.
Im currently using Foxfarm's Grow big and diluting it good I think .

List of the Stuff i have
Foxfarm Ocean forest with about 25% of perlite
600 W MH for veg
4x4x6.5 Grow tent, It can get up to 90F sometimes

Maybe its stress from the transplant, it thought it was gonna die and used nutrients give it a couple more days if it continues to grow fine, its fine. The fan leaves provide nutrients to the plant. Or nut burn (too much Nitrogen), or over watering how often are you watering? You can turn it to 18/6 whenever its just 12/12.

its only a couple leaves, i would only be worried if it were the whole plant or it was spreading rapidly

They are actually looking a little bit better i think the transplant shocked them a bit. The plants are in 24 hours of light but i can change them to 18/6 whenever. I also water everynight at about 8-10 Pm. Im going to cut off the yellow leaves to promote healthier grow.

I'd def go to 18/6 now, and give them a lil N-rich feeding, and that should solve the yellowing issues... It happens when the Nitrogen levels have been exhausted, or nearing exhaustion, especially with younger, thriving plants... I kindof use it as a sign to transplant my young ones, and begin a proper, light feeding regimin... They r looking alright though...

A few of mine (3 out of 23) are doing the same thing. However, my babies are much bigger maybe 2 times bigger than the pics you've shown. I did my transplant to larger containers 3 weeks ago, but the yellowing just started 5 days ago. They are all in the same soil (Happy Frog) and under a 4 ft flo with 8 bulbs. The others are doing fine. I just started 1/2 tsp of NovaGrow to a gallon of water a week ago.

Try some maxicrop plus iron. its great stuff and its been proven that iron plays a role in thc formation aswell as healthy green foliage

U talkin about their liquid seaweed? with iron? The 0-0-1 stuff? I love that stuff... Dont ever see it with iron though...

Check out the plants i love the way they are growing. Give me some good input on the plant's ... GOOD INPUT= HAPPY GROWER

They look like happy little indica dom plants to me man... They r almost ready to be transplanted into larger containers, and probably are not far from showing preflowers... Yer well on yer way bro... Keep up the good work... And think about getting a 600W HPS for flowering, if u only have a 600W MH as u described above... I use both types for veg and flowering, and can't speak highly enough of the results... HPS and MH = VERY HAPPY PLANTS, and therefore = VERY HAPPY GARDENERS!!!

Thank's a lot man i really appreciate you checking out my plant's. I actually do have a 600W HPS so when they start preflowering i will start that 12/12 hour cycle. And if its some Indica I'm going to be a Super Happy Gardener lol.

you should definately not be watering every night, its better for the water to run through the plants and create some run off. its healthier for the plant to cycle through water then kind of dry up and you only have to water a couple times a week in veg.
