m0useanswered grow question 10 months ago 7,5 is not to bad, also you can use commas in place of decimal points.
Soil manages its own PH quite well, but if you wanted you could add in something like a probitoic for the soil and the bacteria and fungas will keep it a bit lower.
I like lacobacteria for this. I made a diary entry on how to make your own. Or you could use a PH down product. I would not go below 6,2 in soil though, I aim for aorund 6,4-6,8 overall of the feed going in.
Good Luck!
