neo... that solution...
1ml/gal ^ 2.0dkh
since it also raises pH, i suggest only increasing by 1.0dkh in a 24hr period.
if after raising 1dkh your pH gets up to 8.3 or higher, you can use 1 teas of baking soda per 50g to raise by another 1.0dkh and keep your pH the same (accute pH decrease, but jumps back up quickly as long as not overdosed)
the way in which you raise dkh all depends on your pH level
