New Grower Auto Mazar grow need PH advice

[AutoUK]

Hi AFN,

I have some questions about my Ph and any advice will be greatly appreciated.

The other day i decided i really should know my soil and water Ph so ordered a test meter.

Tap water 7.5

Water with nuets 6.8/7
run off after feed 7.5

So does that mean i have a soil Ph of 7.5-8? if so i must have some sort of salt build up/Lockout?

To solve this shall i flush with Ph downed water to lower Ph and to help with salt build up?

Good idea.Try and get your runoff at seven or below,your not that far off.
