"Wobster, the issue being asked about is pH, not TDS/PPM. I was aware of this but I don't think you were.

Well apparently you weren't aware that it DOES matter to monitor your PH. Sit down and shush until you can learn to spread good advice."

To Wobster, sorry for the ding, however it just looked at that moment that you were off topic. My apologies.

To daihashie, I was saying don't fight pH. Check if you want, it's good that people do, but I've grown some killer plants without checking either pH or ppm, so perhaps I should have said that to be clear and yes, I guess I'm a little biased. The words "don't fight the pH" shouldn't be confused with "don't check the pH." Not the same. I was surprised by the response my words received in this thread. I find it hard to believe that lowering ppm with aid in solving a problem. Wobster didn't state how long ppm should have been lowered, so it was confusing. Stinkattic has it right by simply saying she doesn't see anything wrong with the plants. This is what I meant when I said don't fight the pH. If you have the time to keep a 6.0 pH and it works for you, by all means, do it. It's funny I get told to shush when Stinkyattic comes along and contradicts those who are telling me to be quiet. So the pH stabilizes at 6.5? Why insist pH must be elsewhere when plants look good? I have grown six foot plants without checking a thing. I'd show you pictures if I had a digital camera. The only real problem we face is being unable to ask plants what they prefer. About molasses, doesn't that work only with bacteria in soil? There won't be much bacteria in hydro, right?
