I use the Pro Grow for veg and 2 weeks into flower.
The Bloom then takes over for the balance.
An additive of CalMag 2 weeks into flower.
Molasses all the way through.

Veg - I start out with 1/2 dose and by second time up to full dose.
Same thing for bloom.
I've been very happy with the results and would not stray to another brand.

I have not tried the sweet or karma.
