advanced nutrients solution ph won't come down (urgent)

OP the simple answer here is Buy a different nutrient. There are many base nutrients for next to nothing, maybe try megacrop.

All these fancy bottles are a joke anyway.
I have the FoxFarms line didn’t like it but the soils are good. I’ll buy some of the Megacrop and try it out. I’m all about saving money if it’s cheaper. Thanks
