@MedMan1878 in the meantime is there a pet store anywhere nearby? They will have ph test kits for testing water in fish aquariums.
Otherwise you can’t go by anything claimed on a bag. MJ like 6.5 in soil and 5.8 pH in soiless mediums.
They are claiming 6-7 that is a huge range and that isn’t reliable without testing it.
It is the water that you need to PH.
