Quick google :thumbsup:
So the soil seems to be optimal for its pH level. Have you add garden lime to the soil? If you have, that might have raised the pH to seven or over. Nutes usually bring the pH a bit down. To lower pH and increase acidity you can add sulphate of ammonia or urea which are high nitrogen fertilizers. Maybe try it to one or two plants and see if that helps. If your pH meter still shows 7 or over, test it to make sure It really works(unless you already have). You can pee on it

Oh and keep the needle in the soil for good five minutes.
I have a PH UP and down buffer solution, this should work its what Ive been using to bring it up or down when I have to use tap water.
