I just got a ppm meter have not had one for most of my grow have about 4 weeks left till the end of flower. I have been running advanced nutrients seni bloom and some of there additives and I have had some nute burn on the tips of my leaves since about the middle of veg I followed advanced feeding schedule but it must be to high based on the nute burn. so my question is now that I can read ppm what should it be at there is no info on the advanced schedule about ppm . my understanding is that you want the ppm of the run off to be the same or less then what you put in to determine if the plants are able to use what you are feeding them if its higher then make the mix going in less. Also does any one know what kind of ppm I should shoot for in veg . the guy at my hydro store said advanced is measured on the 700 scale but could not tell me what my ppm should be . Thanks in advance
