Got a PPM meter and read my soil run off in my flowering plants...ended up being 500. Couple of waterings later I have it down to 290. Is that too little? And what are the acceptable ranges of PPM for soiless mix runoff?

I wanna dig this old one up to help get an answer. How high is getting to be too high for soil runoff PPM?

I’d like to know too cause I have the same thing happening,like 3000+ ppm runofff

I don't do it.. never have, never will.

If your in soil, why? You dialed in the strain right? Then why?
If you don't know how to or what is dialing in... Then I suggest you learn.

ppm run off is not much of a sign of anything useful. It will change at differing times in the plants grow, as the plant uses differing amounts at differing times...

Environmental effect on the plants metabolism will change things alone..

If you know whats going in is right. Then what does what's coming out matter?
Unless your in Coco, why are we doing any run-off anyway?

If you are using an organic soil, like Fox Farm or whatever, checking ppm doesn’t matter at all.

Soil runoff is basically meaningless. What gets me is the people who's plants look just fine but then they decide to check the runoff for pH and EC. They freak out when the runoff falls outside the parameters they think it should be. Now remember that their is nothing wrong with their plants but they become obsessed with the runoff. They then start dumping tons of water through their pots trying to get the runoff to match what they think it should be. After that their plants start going to shit so they flush them some more. In the end all they did was cause their plants unnecessary stress and end up with crappy plants and a piss poor harvest. I see it all the time on this site and others. Usually when you point out the error of their ways they ignore you and instead listen to some newbie posting some chart of plant deficiencies and telling them to flush with a CalMag solution.

High tds runoff is synonymous with fuct up soil. Quality soil can't be rinsed out. You should be able to drink your runoff. If not add some authentic dirt to your shitty artifical potting mix.

The first 3 comments are wrong. Making the last one, moot (Besides being trolling)
