Question about nuts and ppm

simple question for a noob here- trying to understand ppm. Which i know what it means by itself- trying to find the relationship between nuts and ppm.

So im assuming the more nuts you put in the water, the higher the ppm becomes?
and you want to find a nice balance between ppm and nuts?

btw this is for a hydro setup- non-soil
 
There are a few conversion rates built into ppm meters, the common ones are typed like @5 or @7 so all ppm numbers are not the same but generally speaking hydro growers usually grow somewhere between 1000~2000 ppm, lower for new plants, clones and such.
 
hmm now with that said- lets say i have ppm of 4000-would that automaticly mean i can expect nut burn on my plants or can i have a insanely high ppm and not expect any nut burn?

right now- i have a ppm of 1050, but my plant is showing signs of nut burn. im trying to understand how ppm and nuts affect a plant
 
a ppm of 4000 would kill your plants. If you are seeing nute burn reduce your nute strength by about 20% for that stage of growth.
 
so basically all ppm is is the amount of nutrients your measuring out for example 10 mL - to 1 gallon of water (Full Dosage) 5 mL - to 1 gallon of water (Half Dosage) and ppm is just an exact number of the density of your nutrients to water ratio?
 
It measures the electrical conductive current in the water which is the salts and shit in there. Pure water would be zero. My very good tap water starts at 80, really bad well water can go up to 800.
 
so do they sell like ppm down before you ph it? or how does that work I am a little confused what about TDS how does that play into the equation?
 
They sell Reverse Osmosis filters to take stuff out of really bad water but most tap water is fine to use, it actually has cal-mag in there to begin with and if you use R.O. you have to buy cal-mag and put it back.

The idea is that once you reach a certain strength that is too strong it will burn your plants. Each garden and style of growing is a little different but people can give you starting points.

If your water was say 800 ppm and you wanted 1200 ppm there wouldn't be a lot of room left for your food, you'd be over. In that case you'd want to filter it to get it lower but even a brita can filter some I'd imagine. If you're tap is anything under 300 I'd say just use the tap and see how it goes.
