What I see is some plants that are looking healthy. That strain is naturally kinda squat, so some stretch could benefit. It looks like flowering is about a week away based on how the growth tips look. The green is a healthy medium.
You could go either way on the Grow Big. I see no claw or dark green leaves. The
Grow Big is pretty mellow in terms of nute burn risk in my experience. If it was mine, I’d water with about 1 tsp/gal each of Grow Big and Big Bloom then see how the plants look in 3-4 days. If yellow tips or claw starts creeping in, the, hold off on the next feeding. I’ve only had one grow where that dosage caused any burn and it was in some soil that was already hot with a strain that is sensitive to nute burn (Sour Stomper).
