howdy all... i had ten (4 week old) plants growing in soil, in a foil-lined open box under flourescent light, staked them, light fan circulating in room, periodically fertilized with 23-19-17, watered every other day...........were doing fine until recently......lost about five plants in the last week. they looked real droopy, almost as if their "heads were hanging down."....eventually died. i haven't a clue where i went wrong. sound like an over- or underwatering problem? it's a bummer. any advice sure would be appreciated. thank you.
