Cider titration kit %

First time cider maker :slight_smile:
I received as a gift a lot of apple juice yesterday as a gift of local orchard. 60L ofJonagold, 60L of MacIntosh, 60L of Russet and 60L of Northern Spy.
I know, super crazy!
So I’ve added cambden tablets, my ph is between 3.2 and 3.4 depending of the juice and all of them 60L have titration % of 0.3%. Is that too low?
I’m going to have fun with splitting all of them in carboys and trying different yeasts. The Jonagold was amazing juice!
