When I was doing soil indoors I only feed 1x/week at most because I had already seriously amended the soil.
I agree, those ladies are too yellow too early (I would be SO happy to see that in week 7, though!), and at this point it's too late to push enough nitrogen to get them greened back up. I speak from experience to say you don't want to do that.
But they'll still need some nitrogen to get to packing on those buds better. Low, but still a small extra push. If you use beneficials at all then you could re-inoculate, including some molasses and a bit more nitrogen to help foster both microbe growth and leave some N immediately available to the plant.
Worm casting tea with seaweed might be the ticket here, too.
