FloraNova PH question

Hello all. I've been watering in veg with plain Crystal Geyser going in at 6.9 and runoff at 6.3.
However I have started 12/12 this week and begun FloraNova bloom. Same water now goes in as 6.2 and then 5.8 runoff, because FNB lowers the PH. I then tried tap water at 7.5 pH which came out as 6.5 runoff and 1040ppm.
My question: Should I just stick with the tap?
