Normal yellowing or nutrient lock?

  1. sorry for the repost just want to make sure I don't kill these
    I am through week 6.5 since I flipped to 12/12 and the plant on the left is rapidly yellowing. It's a Blue dream strain under a 150w hps, soil grow using Fox Farm nutes and soil, I've tried to add extra Grow big to add Nitrogen and Magnesium but tough to tell if this has had any positive impact. I know it's somewhat normal to have the plant yellow late in flowering but want to make sure she has enough nutes for another 2-3 weeks...
