How do you fix this

All new growth is growing out yellow, bright yellow. I'm no genius but I do know its not right

That's no good, man. What is your water's pH? What kind of medium are you in? That is absolutely a non-mobile nutrient deficiency, possibly iron, which would most likely be caused by improper pH in the root zone.

And what happened to the bottom of your plant, deficiency or did you just decide that your plant didn't need it?

Iron deficient...?

Iron is a pretty common element in soil, so it's unlikely that it's actually deficient. It's more than likely locked out by pH or the action of another element. But we'll never know if @jkl81 doesn't provide more information on their feeding/watering habits.

Possibly bad feeding habbits, I'd post up what dtl asked.

It does look like Iron deficiency. Sometimes a cannabis iron deficiency (like all nutrient deficiencies) can be triggered by stressful conditions, and the plant may recover on its own after the period of stress is over. Easily the most common reason growers will see an iron deficiency is if the pH at the roots is too high. Iron tends to get locked at at higher pH levels, especially when the pH is above 7. So check your PH and if you've been doing anything to your plant that MIGHT be stressful, take a break from it and see if it recovers.
