PH will change with temperature and if you pump a lot of air though it.
6.5 is good. if that's what it takes is just letting it sit out do it.
I have never used that type of soil meter as they tend to break really fast and are not overly accurate long and mid term.
their is also no way your soils PH is 2 or below and them plants are not dead as dirt.
that meter is broken.
Good Luck

Hi Barbara grab yourself a bag of aluminum sulfate, 8.99 a bag at depot store.
Apply to every 2nd watering using the recommended dose.

Aw yes your right, its backward for some reason. and I was using the numbers on the wetness scale.
so yea temps and air dissolved in water will change its ph.
My tap water is 7.4-7.6
When I bubble it it goes up to 8-8.5
I then need to use even more PH down to get to to 6.5.

Plants deteriorating rapidly, pls helpPlants not looking good! Help!
White tips at the end. Brown patches. Leaves curling.
I've been feeding it 0.5L Advanced Nutrients Coco Big Buds.
The light was fairly close, at 30cm. I've raised the lights to 60cm.
It was also very humid, so I've opened the air vents .
