At the moment i am using J Arthur Bower’s Ericaceous Compost which according to the MSDS sheet has a ph of 4.0 to 4.5.
However it doesn't stay that low for very long especially if you are watering with domestic tap water which in our case has a ph of 7.2
I try to maintain a ph of <5.5 and to achieve this i add distilled white vinegar (acetic acid) to the water to bring the ph down to <5.5.
I used this method for lowering the ph in my hydroponic bubbler when i was experimenting with DIY nutrient so that's where i got the idea.
