You need to do your homework.That's the problem with your posts Tim. You give your opinion. ppm is the component that drive pH. How can you read that the OP is using so much fert and still feel good about potassium? Oh right, it's the cations and anions... and just your imagination. Bad info in these forums does nothing but mislead people. If you have to qualify your posts by saying it's your guess or your opinion, then don't bother typing.
No offence.
