Agua Flores ??

Hi all.....Im using agua Flores after vegging with agua vega and havent had to worry or be concerned about the ph values as the solution has regulators within itself.
Flores is meant to be the same but my regular reading is 6.5/6
Im not sure whether to add down or to leave it. my current and steady ec reading is 1.5
the water is hard here but it is all filtered.

Thanks in advance
for any ideas
