So for 20L wort you add 4ml to get 0.4 ppm Zn in the wort

Hi RobW
I think you putting too much zinc into the wort. From my readings, you only need 0.15 ppm of zinc for the yeast. Have a read of this paper whcih describes some results from achieving the correct zinc level. They only add 0.1 gm/l of zinc.
Cheers
Pedro
