Please anyone explain me how to prevent nutrient burn , and how to read ppm run off, for example I got 1000 ppm in and out what’s that mean , and what’s mean if I got run off less than in

if u put 2 ltrs in u should get about 500ml out around about that u stop nute burn by stop feeding them

I mean when I got 1000 ppm in and than got 250-350 ppm run off, and other case I got 1000 in and 800-900 ppm out what’s the difference between those ? Can’t get that part ...

Some strains I noticed can not eat anything and she’ll only really like 500 ppm of food at a time but my other strain easily eats 1300 ppm

1000ppm range should be for flowering thats right never said it was to high for flower
The reason why I got confused , as I don’t understand . When I’m watering with 1000 ppm and MY RUN OFF IS LESS OR MORE THAN THAT ,what can I know when I see those different numbers ... it’s like she’s still wanna more watering , or need more concentration ...




For example , I fed my plant with 1000 ppm and than I’m checking my run off , and I can see the 250-350 ppm ( FOR EXAMPLE) What’s that suppose to mean? Like the plant took 700 ppm outta 1000? Means 300 were excessive? Or it means the plant is hungry and it still need 700 ppm to feed her right...

Yeah, that’s what’s happened back in the day... mazar was a bit over fed, and Mexican haze was doing fine ... same tea...

If Run-off EC is Low:
It is less likely that EC of the run-off will be lower than the inflow. Normally, when this occurs it is temporary and self-correcting within 4 fertigation events. If it seems to persist, there may be a problem with inadequate distribution of water during fertigation events.

You dont have to do this as long as you have run off every day and your nutes are at the right level.

My ex is at 1.8 and I make sure I get lots of run off every day to avoid salt build up. That's it... simple. You dont need to measure run off and all that shit

If you want to prevent nute burn - just reduce the strength of your nutes......pretty simple.
I never check the ppm's of the run off.......you'll run yourself ragged checking it all the time.
If you feed low nutes pH'd to around 6.0 every day to substantial run off you will never have problems.

Why are you checking the runoff? Worry about what goes in. If you take care of that properly you'll have healthy plants. Decades of growing and I've never bothered checking runoff. Coco or soil. I've always just worried about what I was feeding. This runoff checking is something newer growers started doing in the last few years. Most likely because some crappy grower on youtube was doing it. Too much crap regarding growing is becoming mainstream.
