My only initial concern would be the sulphur, as there is no way to equalize a soil and not effect all the other amendments within that soil when the soil has that much sulphur in it. Yeah with that much sulphur in that mix, your plants will have all kinds of trouble uptaking things like Calcium, Magnesium and Zinc. Anyhow to me, a few of their middle term analysis guideline / baseline ranges are way off. From what I have been taught through the years, is that the minimal / optimal ranges for the best soil to grow cannabis in are below.....
P = 40 - 60
K = 60 - 100
calcium = 400 - 800
copper = 4 - 8
zinc = 4 - 8
iron = 40 - 80
manganese = 6 - 10
sulphur = 30 - 50
boron = 1 - 3
magnesium = 60 - 100
And one special note... the total sulphur content rate should always be within 20% of the total phosphorus content rate....
example... if P = 60, then the optimal sulphur content rate would be 48
