Test pH Often

As some of you know, I'm doing a lot with hydroponics. I assumed the pH in my water was a constant 8 as it was all last year and in September of this year. It changed a couple of weeks ago to 6.8 or so and it is doubtful my tomato plants will survive as I was adding acid as if it were 8 without checking since it had been consistent. Don't ever do that without verifying the pH prior to adding acid. That's why doing this ahead of time is important, get the mistakes out of the way while there is something else to eat.

Very interesting that the pH changed so dramatically just like that!!!
