How do you know when plants are getting right amount of ppm? I'm doing dwc and flood tables. Does the ppm stay the same while ph drifts up? or do you keep upping the ppm till you see tip burn?

By adjusting the ppm and ph of your reservoir and checking them with meters of some sort. I adjust by look ie overall health of the plant. I never go past 1.0 ec
