high ppm = high nutrient content = either you'll get burn or salt lockand if the ppm is too high what happens too the plant
mass is on it as usual!if the ppm is to high is it what causes nute burn?
correct smile!I'm guessing that plants in nature also sometimes have access to more nutrients than they need. Do they just keep eating till they burn and die? That doesn't sound like a very good survival adaptation. Surely plants have the ability to regulate what they uptake. If not, why don't my pot plants in hydro, just "eat" the entire week's nutrient supply when it is given and burn from that?
I'm thinking hydro and wondering if nute burn isn't just a garbage term that describes all kinds of things none of which are simply a matter of too many nutes. It sort of doesn't make sense that plants are physiologically compelled to take up more of any nutrient that it needs, especially to toxic levels.correct smile!
a plant is just like most other species of human / animal. they will only eat what they need, an leave the rest behind causeing probs in the medium.
soil
it is somewhat of a garbage term. the term itself is all wrong , because a plant simply can not be "burned" by food (unless you spill it all over them) and your right "nute burn" could be anything , all that term tells you is that the prob started by putting too much food in the medium.I'm thinking hydro and wondering if nute burn isn't just a garbage term that describes all kinds of things none of which are simply a matter of too many nutes.
