Using Fox Farm Grow Big for veg and Flora Nova Bloom for flowering?

I currently have a bottle of ff grow big but in the future I want to switch over to the flora nova series. However, since I have almost an entire bottle full of ff grow big left, I don't want to get rid of it so would there be any problem using flora nova bloom for flowering or should I stay within the fox farm line for now?

I don't think it matters what medium you're in, you can mix and match veg/flower formulas with no issues.

what a relief! thanks!
