[OTE="Dr. Who, post: 10687355, member: 378146"]Yeah, simply pH anything your watering the plant with to 6.5 before you water.
Now don't worry about the pH of the soil as it will self pH to the specific plants needs, as the living bio's in the soil adjust to the plant. (with the use of a quality soil)
If you attempt to pH the run off. all your getting is the run off's pH,,,,,NOT the pH of the soil!!!
Soil pH "swings" naturally !!
When watered, the pH of the soil will rise. As the soil dries back out,,,,the pH will fall back down. What this pH "swing" does for the plant is to cover the range of optimum available uptake requirements by the various nutrients to be "used" or "made available" to the plant in relation to the pH of the soil.
If you would like to understand more about soil pH and the living things in the soil that go a LONG way in controlling it......I suggest you buy and read this (a must for anyone wanting to grow organic);

If your using synthetic nutrients,,,be SURE to use a "zyme" product to keep the living bio's in there and working.
You knew that Racer. You just wanted me to clarify, didn't you?[/QUOTE]
I check my runoff when my runoff is not in the proper feeding range I check runoff get deficiencies
