Can you do a tap water test?
Just pour a glass of water from your sink and let it sit for 24 hrs open to the air. Then test its pH.
This will allow for any off-gassing to occur.
Your pH can change quite a bit.
You may not need to buy bottled water unless where you live has warnings about not drinking the tap water due to contaminants.
You also may not need to change the pH of your water. The soil should buffer your pH. If you have very alkaline water it could be a different story.
Some places have a municipal water report online. You can see if you have access to one where you live.
The pH swings and/or total lack of food are killing your girls.
