Starvation is not a valid growing technique. Even if all you give them is Grow Big...I'd feed those ladies per the Fox Farms Feeding Schedule. Fox Farms Feeding Schedule...
Just went 12/12...? Grow Big is not a bloom fert, so you'll have to make changes there. I'd go with the Tiger Bloom. (I use Fox Farms myself)

A little low on the ph, as ph in peat-based soils drift downwards. it's nothing major yet...but something to keep in mind.
