An accurate pH level is essential for your plants to ensure optimal nutrient uptake. pH levels are adjusted by using 'pH Up' and 'pH Down' solutions. pH pens also need to be calibrated every now and then in order to ensure an accurate reading, this is done with the use of 'calibration and/or buffer solutions'. Look for the calibration instructions of your pH pen in the instruction manual.
