How would growing hydroponically deal with the issue of mildew?

David

Its probably caused by too high a humidity. Commercial hydowponic growers
measure humidity directly and will use an exhaust fan or some passive
mechanism to reduce humidity.

If you are worried but excess moisture on the leaves then dont water the
leaves, only water the roots.
Commercial hydropinic production is heading towards nutrient film techniques

No soil or other growing medium. Roots are suspended directly in the
nutrient solution. Nutrient solution is pumped regularly over the roots - at
other times no nutrient solution is passed over the roots so the roots can
absorb oxygen/CO2 and reduct root rot.
