Yes those are fine, Bio-bizz is a very respectable company. Plus you already paid for them so why go with something else. If anything I would just get some sort of catalyst/micro nutrient to use during the entire grow since you already have veg and flowering nutes.
I use the Fox Farm's trio, so I can't say I have any experience with the BioGrow and Bloom. I use Grow Big for veg, Tiger Bloom for flower, and BigBloom throughout the entire grow. I also recently picked up some unsulphured molasses to add to my flowering plants since it adds Potassium and a lot of micro nutrients and makes your buds really swell up. You can get it at the grocery store for like 3 bucks, just make sure its unsulphured.
