Ppm for organic soil runoff

[Twedjr]

Hello everyone I’m a novice grower who has primarily been growing in hydroponics. I’m now about to plant into 5 gallon grow bags filled with super soil in the bottom half of the bag and plain potting mix on top with the middle mixed together with both. My question is what should the ppm be in the runoff? I’m getting very high readings of around 2500 ppm even after flushing with 3 gallons of water. I don’t want to burn up my seedlings and on the other hand I don’t want to flush all the nutrients from my soil!!! Please help me if you are growing in organic super soil!!!

I believe with organic or living soil you don't really flush. It leaches everything beneficial out of the soil.

Microbes will break stuff down to make it plant available. I don't know what the runoff ppm would be. My last organic grow I thought I was cooking them. So I flushed and the readings I got were high like 2000 ppm.

Hopefully someone has a better answer for you.

PPM is more a measurement (concentration) of individual elements or compounds, not the big organic molecules you have in organics. The PPM is only showing soluble salts—nutrients dissolved in water, immediately available to plants. So pretty much worthless in organic soils. You can track changes, but the specific number isn’t indicative of nutrient availability. And no reason to flush the soil or have a ton of runoff.

The available concentration of salts for plants in soil fertility is about 1ec . You need a balance of elements, as if it were the perfect soil.

I wouldn't add the soil in layers like that, I would just mix it all up evenly. I'd be worried about the plant developing nutrient problems because it grew into very rich soil at the bottom during flower. I've grown in Natures living soil before, and if you don't mix it up very well, it leaves nitrogen hotspots throughout your soil.

No, I have more than 50 liters of earth that I have used for 11 months, nothing like this happens if you follow the irrigation regime and observe the physiological composition of the nutrients in the solution. All other options indicate an imbalance, and there is no other reason.

Then you know exactly what you're doing, and don't need help from anyone. Good luck.

I water my organic soil before planting in it,

I agree with this, mixing is your friend.

I am all Organic including nutrition but not super soil.
First have you added anything to your soil at all. When you runoff an organic soil the ec is the nutrition in the soil leaving the building. It is not required. In organics you do not even have to pH water. The ion load of tap water is misleading. If you can drink it your plants can drink it.
Super soil has a learning curve for setup ( I do know that much ) and there are tutorials available online to help.
Now as a new grower look up proper watering practices. Number one killer for new grower in soil. Also perhaps you could try the search feature. Search for living soil under grow diaries and read as many journals as you can. You need to fill in some missing knowledge before you pop them beans.
Wish you some of the luck as I need some too.8-)

Yeah in fact I know people that grow in organic soil with absolutely no drainage. like a 5 gallon bucket with no holes.

Organic soil is basically 1 1 1 but it is a huge reservoir of convertible nutrition. If you had the same amount of 1 1 1 chemical ferts that is in organic soil it would catch fire quick. The biome in the soil self regulates the nutrition. You will get painted nails and deficiencies and fade but unless you add something you should not have you just can not burn a cannabis plant.
So called hot soils are easy to explain. Sorta sealed bag got wet biome turned on and without oxygen it drove pH up. These mostly kill seedlings.

I also run a living soil, not a super soil. Coco loco and NLS concentrate. I water when my pots are light, and then water enough to get just a tiny bit of runoff. As said, you want to keep that organic stuff in your medium.
