Trying something today. I thought I had given up with pH down, because when I measured run off, and this was like 3 months ago, of pH6 water in it came out pH7. So I said I'm wasting my time pH downing because it's buffering back to 7. Now's week 7 and some plants have more yellow leaves than others. Excluding sativas in this comment. But anyhow, I don't know what I'll be able to tell if anything from doing this but I'm back to pH downing for now. I don't get much runoff and I don't know if I'll bother measuring that again.
