I nothing on ppms?Going to read up on that.
ppm - parts per million , shows how much of your soil is fertilizer , the NPK is just what % nitrogen phosphorous and potassium is in the fertilizer
if your PPM is to high then your plant will take in to much and will result in burn and most probably a lock out from salt build up from all the unused fertilizer .
again not the best guy to be telling you this cuz i used lime to balance mine since am organic my ppm and PH are pretty manageable. i don't even have the meters , well i have the ph but not ppm but haven't used the ph meter in forever
