Well I grow in soil and I mix up RO, CalMagMax, some Big Bloom and then the Tiger Bloom in various strengths for feeding during flower.

I'm starting with plain RO water that reads pH of 6.6. I've heard that RO water lacks 'buffering capacity' (whatever that means) so it reacts very drastically to substances that raise/lower pH. Maybe that is part of the reason why the TB has such an effect for me.

I was just told today that if I add the tiniest drop of pH UP to my RO water, it should snap right to a perfect 7.0 pH! I'll have to try that tonight.
