First time testing PPM and slightly panicked :c

1st. Don't panic 2nd. In coco the output ppm is always higher than the input , it's due to the nutrients accumulation in the medium so you always need to check the input and the output values as it's a constant management to correct the fluctuation between the input and output so if it's the first time you're checking I am understéanding your confusion. 3rd. The ph can jump like that , it recently happened to me with a Berry ryder ( auto ) that I've flushed because of a ph too high and a high amount of nutrients , the flush did removed the nutrients pretty quickly but the ph get from a high value to a ultra low 5.3 without any clues of what was happening. I still don't know what happened , what I know is that I've watered many time with the proper ph to get back to my 5.8 value and that I had to put nutrients back in the mix because of the multiple flush BUT my plant was better after less than 24h and even the smell were more powerfull. 4rd. Some nutrients are responsibles for the ppm in coco , when they are flushed then the ph is switching as there is no more buffer

hi dude.....! give to an auto 2200pm (even with co² intra) i can understand you are panicked...but take breathe what is done is done......anyways flushing was a better solution than let the plant staying with that... u have to pray at this step sometimes a ph meter need oftently to be recalibrated.....whatevever next watering also with fresh water may be to the final flush good luck buddy
