This actually depends on your final purpose and soil. A lot of people ask similiar detailed questions, and they never talk about the plant for which their fertilizer is intended, nor the soil or substrate in which said plant resides. Or the plant. Well some do, but not many.
Yes if you add an acid, citric or otherwise, it becomes a specific weight issue between 2 liquids and said acid may be a issue given you are bubbling what is usually considered a bacterial tea formula given the carbohydrates you are feeding it. The difference between 7.65 and 7 is fairly large. It seems you have a digital pH meter. Hydro? Do you have access to a 400x microscope? You can see the bio with a scope of that power.
Which bacteria are you propagating and why? Worm compost is simply a denser and more available form of nutrients than the material from whence it came, and a tea is a growth medium like a tetri dish in a laboratory for expanding a sample of bacteria or fungus, that latter preferring more protein. Why would you prefer a concoction that is less dense? Organic fertilizers are often not as strong as folks think they are as it is, which is why I am asking.
and some others do this often. Seriously though, I imagine they would want to know what you are trying to do with the tea.
I have only tried to use tea as a medium for antibiotic activity myself. You will not hurt anything if you kill your tea. The molassess will be good for the soil.
