you might need to ask the manufacturer/retailer, if it can be used in DWC.

or even get some and test for yourself...

is it cheaper? or it's in bulk volumes? is that why, you're looking as such?

Those are 10 kilo bags. Maybe try something of less volume to start. A single Kg will last any indoor grow a long long time.
Both of those are really really high in K, you may want to look into something with more P especially for the bloom cycle
