looks like it could be pH to me from the twisting of the leaves, adjust your pH and you will see a visible difference in growth. with a perfect pH the plant can grow to its fullest potential without waiting for you to fix its pH. the yellowing can also be from nute lockout caused by an imbalanced pH

Yer points to ph being out. Soil looks very dry to me and like a big pot for a small plant, how you watering it and i doubt you will have started ferts yet but if you have which ones? The plant looks quite bad and kinda like it needs fixing now or it will get a whole lot worse. Have you pH tested etc yet? What about too much heat from the cfl let alone the hps??

Jet Li, hey buddy, why are you budding a plant this small? The ph is hard to control when you have such a large pot and a plant so little, the roots aren't getting evenly watered, and are probably growing into patches of soil that are totally void of moisture...so really the fix here is matching the right size container with the various stages of growth.
I use three container sizes ...a little 2"x2" for seedlings and clones, then 4"x4" for that 'in between' stage, and then their final container(2 or 3 gal containers) to finish vegging and for the rest of flowering.

thanks for the advice guys. this little fella is about 8 weeks old (i know very small for 8 weeks). It was started in a solo cup using fox farm soil. we are not flowering yet, its still on a 18/6 light cycle. no nutes yet but we use fox farm products. once it started yellowing we tried to rule out problems one by one. First we checked over/under watering. We left it unwatered for about a week until the soil was dry all the way through. No improvement. then soaked it through and through, continued watering every 3-7 days as necessary. Still no improvement.
Checked heat and light stress. It's definitely warm in the cabinet but i have no problems holding my hand over the plant (gets to like 85 during peak heat, usually leave the doors open and it hovers around 78-80). My friends had no problem growing in 95 plus so i dont think its that, but could be. Maybe to much light? Thought it might be stunted roots in the solo so we transfered to a 2 gallon pot at about 7 weeks. Havent tested ph, didnt really think to until you mentioned it. Once we start nuting we monitor closely, but i thought fox farm soil was buffered to an acceptable ph before you need nutes. maybe our water is a little hard and is slowly increasing alkalinity in the soil. whats the best way to test soil ph using a standard test kit? soak it through and collect the runoff after a few seconds? what should my ideal reading be for soil plants...i thought it was supposed to be closer to nuetral when growing in soil, 5.5-6.5 ish in hydro. any advice is appreciated!

Cannabis and the nutrients requires a slightly acidic pH in order for all the nutrients to be dissolved at the time of the roots absorbing the moisture around. I truly dont understand why the pH should go as low as some do in hydro. It doesnt matter how much you change the way you grow, the plant stays the same, it still needs the same stuff it did even when it was in soil, except the soil for example had beneficial bacteria where as hydro didnt...
6.5 pH for me has always been GREEN waxy ass leaves, fully healthy fast growing stress free plant
its stayed that pH whether I go soil, coco, hydro, or whatever..
And bro, I have grown from seed in big ass pots. From what the people replied earlier iits made to seem it is really hard to grow in a big pot when its not at all, you just gotta watch the amount of water you give with respect to the root structure/size of the plant(for example a seedling is not gonna want a gallon of water, the little taproot will rot within a day, and a mature mother plant that takes up your whole closet is not gonna want a cup of water...You gotta make sure not to overwater, and dont underwater, always water your soil mix beforehand so you don't get those dry patchy spots as Punk noted.Cause once the soil is all moist, it ALL stays moist and evenly dries out from top to bottom. Then when you water at the perfect time when the soil is mostly dry with a little moisture so the roots don't starve of h2o. I have always seen the fastest growth with perfect pH, Letting the soil dry in between waterings, perfect temp. You are doing good, I would just say let the soil dry in between waterings, test, and adjust the pH. Do not feed it though until the plant itself starts showing deficiencies. In Veg its fine to have deficiencies, cause you get right to them, and can veg to however big you want it, cause it'll keep growing.
hey man, keep doin what you're doin, growing flowers to their fullest potential takes the effort of understanding what you are working with and how it works.
They seriously look like they want to explode so badly, but something is holding them back, and it looks to me pH, heat just makes it so that the h2o transpires faster out of your leaves hence the droopy leaves. too much heat and too much h2o is coming out and too little is replacing it too slowly. I wouldn't worry much bout heat as long as you got it 95 and below, what concerns me is your pH though haha and ill keep saying that until you fix it and i see her popping out of that container with full life
Looking really good thoughh man

It presents additional challenges and is not ideal. Sure, certain phenos are just gonna take off in big pots, no matter what you do, they love to grow roots fast, but your smaller indicas and slower growing phenos are going to expend extra effort in developing as much roots as you allow it, and less on upward growth. Speaking from experience.

Ok? the plant is the same, it does not change, no plant does, how does nature do it? start it in small dixie cups under fluros? hahaha and btw im not even debating you, or saying your wrong i'm right. just bringing to light that anything is possible you just have to go about it doing it a certain way in respects with the plant itself
