Yellow leaves

You should fill out the form in teh sick plant sticky, else we are all guessing.
My guess: Looks like classic nitrogen deficency. Lower leaves, completely yellow. Often this occurs if you make the switch to low N flower nutes right as you make teh switch to 12/12. I continue to feed veg nutes for first two weeks.
Does not seem heat issue to me, as that would affect top of plant and generally give you "taco leaves".

I agree with Dr-D especially because it is happening from the bottom up. I too phase out my grow nutes over the first 2 weeks of bloom.
Are you noticing a lighter green throughout the whole plant? with extra yellow at the bottom?

It looks like straight Nitrogen deficiency. Even in flowering, Nitrogen is used to build proteins and other cellular structures. The even yellowing of the leaves with no fringing looks like your pH is good. Nitrogen is a mobile element and will be sucked up to the top so you might want to slightly increase your N.

So it is a Nitrogen deficiency then. How do i raise Nitrogen with my fertilizers? Im using GHE Flora series.
Heres a list:
NPK
Micro 4 0 2
Bloom 0 3 4
Gro 3 1 1

You never filled out the rest of the form. Not clear what medium you are in, etc.
Me? I would ditch the grow, use a two part micro/bloom ala lucas, and incrase the amount of micro as that is where your N is comming from. A full dose of lucas w/GH 3 part (using only 2 parts), is 8/16. I feed my coco plants with 4/6, and never see any N issues, and in fact finish too green (I do not flush, and the h3ads approach to lucus in coco stops all micro half way though. I have a mix of young and new so they all get the same thing, up until chop, but that is me.)
In the future keep on veg (some say same lucus for both veg and bloom, but I reverse the ratios to 2:1 micro/bloom for my veg) for the first two weeks of bloom.
