Wow! huge photos..ha,ha. Hey man the plant looks great and I agree with Scarhole...needs some nitro. You could try fish emulsion to start it off. I've always liked a bit of fish emulsion to feed plants with..natural.. and you can't burn the plant or build up salts in the soil.
I'm new here and was checking out your grow. You have done a nice job...looked a bit shaky in the beginning but you turned it around with devoted work to the plants. These last photos looks like you are on your way to a nice crop.
