honestly I water mine 24/7 and I think you could too. The hydroton is plenty airy enough and I have not come up against overwatering issues yet (except for brand new seedlings.) Don't take everything apart.....just check ph as much as you can and keep correcting it. When I have come up against this problem (I HATE hydroton) I've discovered you just have to wait it out and then the next time soak the living crap out of the stuff. But for now just keep correcting as often as possible and change out your water every 4-5 days depending on how much ph up and down you have to use...(again...salts in those adjusters)

i think hydroton generally has a ph of about 7......too high for hydro right out of the bag.

If they were going to croak they'd have done it by now so I think you may be seeing the light at the end of the tunnel here.

Got a LOT of buckets there.....hope your room is big enough to handle all that.

Keep the log updated....i'll check back in and make sure things are going ok if you like.

I still have a bunch of that VHO....been using the Liquid Light but I may make way back to the VHO myself.
