    Ericaceous/normal soil mix for pH issues in soil?

    Has anyone used ericaceous soil mixed with regular multipurpose to grow in?

    I am unhappy with my bud at the moment, the calyxes seem small and underdeveloped in most of the strains I have been growing recently. I have an entire plant that I have cured which I now consider "trim" to make hash with. I am confident about my nutes (75g fish blood bone in 25l of soil mix), my lighting (mars hydro SP3000) and my strains are from reputable breeders. I have been doing nothing to drop the pH though and I believe that normal multipurpose compost is at like 7.5 or 8, my tap water is at 7.9 and apparently I want to be at 6.5 for soil. I had a quick search on here but can't find anyone talking about mixing erricaceous soil (5.0-6.0) with my 7.5 multipurpose soil to make something closer to 6.5. I've bought "pH down" and a water pH tester to make sure I keep the pH down in the water.

    Pelleted sulfur will drop the PH slowly, the plant will move elements around in the soil to make it the PH she wants, lime is its buffer.
    Mix it in to drop PH, why not? I have used peat moss (3.5 PH) to drop PH in my 8.4 soil
