GDI! I bought the "Bloom" for flowering. I've heard great things about Dyna-Gro and decided to go with it. It's my first grow and lost the coin flip between "Bloom" and "Foliage Pro" haha. After re-visiting the Dyna-Grow website it says it's good to induce flowering... I planned on using my veg nutes during the stretch period and the Bloom after.
