Actually you can use FF grow big soil (green) in hydro. Ive used it successfully and the Fox Farm Tech support claims that it a better product than the hydro (blue). The hydro store guy had the same response. And yes do use the tiger bloom in flower. They have a feeding schedule on their website, it should answer your questions.
The trio should last 2 or 3 small grows. And the Big Bloom is not flowering food really. Its more of a buffer and stabilizer to use the entire grow and as a foliar feed(lights off only). Also BB is so low in NPK that it will never nute burn.
Go easy on the GB when the plants are in their first month, it will burn so go 1/4 strength for then first two weeks, 1/2 for two, then to 100% of reccomended amount.
Also, there is no Calcium or magnesium in FF so get a calmag product to add
