Anyone Ever Recieved bad Ph Calibration Solution?

  1. I suspect that the pH calibration solution I am using is not accurate.... As you might think this is disastrous for any person growing weed...  Does anyone have any experience with buying and receiving an inaccurate/bad ph solution?
     
     

     
  2. Never heard of a bad batch myself. but have seen ph of test solution change over time due to improper storage conditions and or contamination.
