pH of water coming out of soil not the same as water going in.

After adding nutes to my water, I adjust the pH accordingly. Occasionally, I will test the runoff only to find that it is out of range to the water's pH going in. Should I be adjusting the water's Ph so that the pH of the runoff is within 5-6pH? I'm using General Hydroponics instructions for drain-to-waste in soil.

Don't be mad, Campesino, I just want to get other's thoughts on this issue.

You have a combination, not commonly seen, and not all that rare either. Before I hazard an opinion on your question, I would like to know if you consider this to be a hydro grow, or a soil grow?

You plants (in soil) will adjust the pH at the roots to whatever they need in spite of you!
All you need to do, is add nutrients/water with a pH close to 6.0 going in.

Run off in soil should be between 6-7 ph. It's okay if it fluctuates. If it drops or raises significantly then it's a good sign that buffers in soil are off.

Thanks for the comments.

It's a full-on soil grow.
