    if value < User.find(:first, :conditions => [''id =
?'',
record.user_id]).minimumbottles
      @min = User.find(:first, :conditions => [''id = ?'',
record.user_id]).minimumbottles
      record.errors.add attr, ''=> '' + @min.to_s + 
'' is your minimum

      the current program, please contact admin to change program

You could add an if statement to the top of your validates_each block as 
such to emulate what validates_presence_of does eg:

validates_each :quantity do |model, attr, value|
  if value.blank?
    model.errors.add(attr, "can''t be blank")

  elsif value < User.find(:first, :conditions => [''id =
?'',
record.user_id]).minimumbottles
    ...
  end
end
