I don’t really notice a difference wether I ph down or not. I’ve been using Promix HP for a while now, some grows I ph down to 6.0 and some I don’t bother and no difference from what I can tell. My tap is around 7.5-8 and after adding nutes it’s around 6.5ish.
While 6.5 isn't optimal it's not a huge variant and depending on nutrients and plant genetics is probably not awful. Now if you were in the 7-8+ range, I bet there's a whole lot more chance of a problem.
