wont it be better to ph the run off and see how far your ph is out 1st befor you start adding up/down

i cant test the run off with ph solution test as the colour of the water would obscure the test result. ph'd the water to 6.2 and crossed my fingers

plain watering should have a ph of 6.8-7.0 I found those drip kits to be a nightmare, when I got my first proper ph tester I made up some feed with a ph of 6.5 on the drip kit, then i tested it with my proper meter and it was 6.1!!
