Need advice please

As for PH, ive been putting 6.5ph in , and last watering got 5.9-6ph out.. this watering i think ill ph to a little over 6.5 and try to get the root zone around 6.2 or 6.3?

For ya ph mate . Don't bother ph'ing what goes in as ya soil will or (should) have stabalizeing buffers already in it . As for ya EC , ya really do need ec meter it's no good guessing.
