Due to a cheap pH pen I was pHing I think between 6.5-7.5 I bought a bluelab pen now so should I start pHing between 6.0-6.8? The plants look good I think so far.1 Week into flower. Any advice is appreciated!

Your girls look nice and healthy and it sounds like your old PH pen was not that far off. I would just carry on with the new pen and aim for 6.5 but anywhere between 6-7 is ok.
