They're clearly healthy. I'd go dig some soil and roots up from under an old tree for your next tea.The microbes are in the roots as well as the soil.Add a dose of grow and top max for food,they love humic acid, top max.That should sort your PH out There's some great posts on collecting microbes on you tube,chris trump is the man with his KNF farming.Id add some PK to fatten those buds up. Wood ash works great for K and shite for P.bat guano really helps with taste as well. Or a cheap bottle of organic PK,10 euro. Top Max is just Humic acid I think which is great but they need some K Potassium to build the cells.

There's a lot to be said about PH and organics, you should check it out.If you start off good good soil with a good population of microbes with good stable food then it shouldn't worry unless you see something drastic. I rarely worry about the PH with my organics.I use a cheap soil probe. Never test the run off but I never have issues with PH.With synthetic I use PH Perfect Sensi from Advanced Nutrients and Iguana for organics along with guano, ash and seaweed. Your plants look fine, I'd let them do their thing.
