Soil runoff PH is high, after checking with a PH solution test kit.

So please forgive me here for asking this question here.
I guess I have to be very precise, in asking a question.
If my soil runoff, is is around 7 to 8PH, after using Distilled water, which is neutral?
I need to PH up to counter the soil?

I wouldn't do anything as long as they are still alive. The soil pH will come down I would think with regular feeding. but all I know is adding strong pH adjusters is a good way to kill a plant quickly.

1.0 point of the pH scale is a 10x increase.

Buffers will maintain a pH rather than change it like an acid or base. Limestone is a buffer and rich in calcium or magnesium depending on the source. usually a bit high though as it is what makes hard water run in the +7.0 range.

Here is a buffer that breaks down to potassium and phosphorus.

Potassium Phosphate Buffer pH 6.5. It will 'use up' H+ (acid) to raise the pH or 'use up' the hydroxyl ion OH- to lower pH to 6.5 until the buffer itself is 'used up'.

What did your distilled water pH at. True distilled water at the point of distillation should be completely neutral at 7, but the minute it hits air it starts to drift downward. Mine usually ends up around 5.8 when I test it. And if I'm using it to water I always adjust to the proper level of 'slightly acidic'

You're up around 7-8, I'd start watering to the lower side of 6, like 6.3 or so. It should help bring the overall pH down in time.

The ph of the water you give has nothing to do with the actual soil ph. It is the composition of the soil itself that sets ph not the water you give... that is ...unless you grow in a sterile hydroponic medium like coco. Checking soil runoff tells you nothing useful. Unless you have a fancy expensive soil probe don’t bother trying to check ph.
If your plants are healthy the soil ph is in already inside proper range for absorption; most bagged soils are ph balanced. If you are feeding synthetic nutrients which typically contain ph buffers then you should check/adjust ph of the solution when you mix it but adjusting the water you give in between will not change the actual soil ph in the root zone. This is because nutrients are absorbed directly while naturally feeding plants in living soil need decomposition in order for whatever is in the mix to be absorbed through cation exchange.

To all who have contributed here, thank you for the information. I do have more than just the PH condition of the soil going on in my pots.
I have flushed the pots with distilled water, under the suggestion of another member. and am taking a waiting game approach to the problem.
