Fox farm nutrients help

I am about day 70 from seed. I’m having trouble with what I think is calcium. I’ve flushed my ffof soil a week ago because I never have and thought my girls aren’t taking in the nutrients since growth has slowed down a lot. I’m growing northern lights autos. I’ve never used grow big since I heard ffof soil was hot, I’ve only started using big bloom, tiger bloom and 5ml of cal mag plus when I went into flower. I’ve given just under full strength of nutes twice a week with cal mag and ph water/cal mag inbewteen feedings. I’m still having a calcium issue. My question is am I supposed to be using grow big also? I read that you should stop using grow big when you go into flower. Need some help here pls
