The water from my tap is 77 PPM, if i use a Brita filter it goes down to 52 PPM.

I bought some bottled water and that is 59 PPM and after Brita filtering is 46 PPM.

I made sure none of the tests werent "contaminated" with each other.

Why can it filter more of the tap water (the Brita) to a lower PPM, yet cant filter the bottled water by the same difference ?

Is 52 ( not far off 50) still too high for CPs, and i take it 46 is ok ?

Any thoughts gratefully received.

You could get away with using your tap water (77 PPM) provided that you flush the soil regularly or simply always water from above and let the water flow out the drainage holes in the bottom of the pots without catching it in a tray.

My guess is that the lower the TDS measurement, the less effective the Brita is. It probably only gets the largest particles out of the water.

will its the salt and if that is low its the other chems and minerals that do it just use rain water it solves all those problems ok

Yeah, rainwater is what I use and is the best solution! You can use the 46PPm and it won't hurt the plants.
