The way willow bark tea stains taught me about soil pH

I was soaking cuttings for rooting last week and noticed the water turned reddish brown, then I looked up that tannins leach out and lower pH around the stems, which apparently helps some plants take root faster. Has anyone else seen this or is it just my local water messing with things?

So my hydrangeas went pink last year and I blamed the rain, but turns out my neighbor dumped coffee grounds everywhere, go figure.
