Soil PH adjustment.

Hello i just bought a bale of a soilless mix and on the info sheet it says it has a ph of 5.5-5.8..
Im using Advanced Nutrients and on the feed chart it says to keep soil ph at 6.3.. so i looks like i need to raise the ph of my mix...
ive been reading that dolomite lime should do this but i dont know how much to mix per gallon of soil so i can get my ph at a perfect 6.3..

I use one tablespoon per gallon of pro mix, but keep a close eye on the ph even then and adjust for your conditions.

Good luck.
