Need Help, or do I?

I'm a newbie on my first grow from a bag seed. I was way too anxious and started with MG, no nutes, under CFL, but around week 7 I bought Fox Farm nutes, and a 400 Watt MH lamp. Once I had all the equipment I germ'd some good seeds (friend donated a few from his online order). Now I have two babies and a more mature plant under 18/6. My idea was to veg the bag seed until the others catch up, and do a Scrog. Now that it has nutes, the bag seed is growing good, but the tops are turning light green and the leaves aren't really spreading. Do I have a problem? I'm open to all feedback, I'm including pics of all 3 plants. I topped the smaller two and did LST on the taller of the two. they are growing way better than the bag seed.

Looking good

Thanks, so you think I can keep vegging the 1st one? I used lst, and it's got multiple tops

You don't have much room by the looks if have room yeah

I've got everything on about 2 feet of boxes. I have a 5 foot tall tent.

You can veg if you have room

Can you post picture of tent please ty

Sometimes when they get pale like that it means they want more food. Also, often the new growth is slightly less green than the rest of the plant at first. Maybe that's all it is.

Anyone else want to chime in?
