Well...I think I know how it happened. Now can I do any6thing about it? This is my fourth batch and the only one that I screwed up. After mixing my batch of soil I put it in the 55 gallon trash can like always then watered 1 or 2 gallons of phed water 6.5. I did not have the lid to the can anymore so I tool a old soil bag and placed it on the top of the soil and put some weights on the bag...hopefully trying to keep the thirps out that were in my garage from the roots soil in another container. Well I think that the thing went anarobic without any oxygen availible to the soil and it basically has rotted I think. I noteced my plants have bright lime colored leaves and couldnt figure out what it was except it was the only plant with the new supersoil. So this morning I did a runnoff test of the supersoil...it was bright orange which is 4 ph or less...off the chart I think.

Could I just add a bunch of hydrated lime and still use it? Or dolomite pellets? Or should I just bag it and go start mixing a new batch?

Also...if you were to be makeing new supersoil today and all you had to choose from was happyfrog, Ocean Forrest or roots organic...which should I use? Im thinking happyfrog with lots of big chunk perlight?

Man this sucks....

Any help is greatly appreciated!

Heres one thing I thought of. I could take a 7 gallon pot and fill it halfway with the low ph supersoil. Then mix in that white powder hydrated lime like 2-3 heaping tablespoons. Mix it up really good then water the pot and wait 1/2 hour then water it again and check the runnoff ph to see if has reached 6.5. If it does then I know how much to add to half a pot of supersoil and I could figure it out from those numbers?

The soil doesnt smell or anything...bad like that. Now that I think about it the soil has been cooking since december or january.

What do you think? Lesson learned right....

Ok...I will try that..Mabey take 4 gallons of ss mix in say 1/4 cup pellitized dolomite.....water...let sit for an hour then check the runnoff for PH and adjust the lime as needed? Can you over shoot the ph adding too much dolomite? I was under the impression that it will raise it to ph 7 but not above that?

Thanks for the reply scroglodyte

sure thing. more like a cup of dolomite, to 4 gallons, with a ph that low, imo. i like to test my soil directly, by making a slurry of some soil, with distilled water. like a milkshake. run-off is a funny thing

Oh yea....thats a good idea. I have a different type of ph tester. Its for continuous monitoring of saltwater aquariums and the probe is shot so Im useing drops. Can I put in to much dolomite? Perhaps overshoot the 6.3-6.8 I want? Also could to much calcium ( dolomite) cause a lockout of some other nutrient I wonder...scratching my head...
