I haven't done this personally - but I think it would work beautifully! And I don't think you'd need any particularly specialized nutrients... especially in the veg state... I would add some bonemeal (or other source of potassium) and some Langbeinite for your phosphorus (top-dressed since it's not easily soluable). Make sure you've got a good source of calcium (pulverised eggshells?) as well.
When I grow in soil, I top-dress the Langbeinite at the rate of 1 tablespoon per month per pot throughout the grow.... Since I use cannabis-specific nutes, I add a PK booster (0-10-10) and one dose of calmag per week from week 2 or 3 of flower....
Good luck... !!
