Robie: so, the yeast nutrient has recommendations for the different strains? If I understand, then, it can be assumed that the provided yeast requirements are met by the kit, so by checking the nutrient needs of both the provided strain and the strain to which you want to change, add the difference? Is there a chart with various strains provided with yeast nutrients?
The nutrient likely doesn't mention any particular yeast strain. Rather, the yeast strain will indicate if its nutrient requirement is low, medium (maybe), or high.
