This looks like classic nitrogen deficiency... she's dying for some food! I'm not familiar with your nutes but it seems light on the nitrogen so I would add some CalMag and see if that doesn't help the issue... those leaves, btw, will probably NOT show improvement but the new ones coming up should... Other than her color, she looks healthy and you've got a good shot at improving the grow.
One thing that would help us help you better is if you link your question (any question!) to a diary... that way, we can see "the whole picture" ...
Good luck, I think the CalMag will work and you (and she) will be happy campers!
