You have to be of the mind that different sulfate compounds, effect different terpene's...
K sulfate is more fruity/grape like in effect result.
Mag Sulfate is more citrus in effect.
Playing with other sulfates to try and zero in more of what terp's they effect - Pine?
I have found through some years of playing.
Most patients and customers seem to prefer a "balanced" use of each I listed.
I go by % by volume in making the supplement and in application.
6% solution of K sulfate and a carb source is delivered at 7.5 ml per gallon.
The Mag sulfate Is a 1.6% (aprox) solution, delivered at the same 7.5 ml per gallon.
Some strains react with the blooming of some new terp profiles. Things there, just more expression.
Most react by increasing at an equal rate.
All get some flavor increase.
I see some increase in trich production and that is always good...
Now only if that Snowball pheno I have would ripen as quick as it bulks...
