ph runoff very low.. please help

[Jungl3Jim]

I just did some experiments with some fresh water, hydrated lime, and some new sunshine #4.. it took me pH 8.5 in to get a runoff of 6.0... what should I do with my flowering plants that have been getting 6.3?

I'd be using dolomite lime myself. From what I've heard straight hydrated lime takes a bit to break down and then get a little hot. May burn ya girls.
Anyone else..??
I'm no expert here
