Try mixing it with "Distilled Water". You can buy a gallon of it at most stores for a $1. Distilled water has no trace minerals like tap water or "Drinking Water" for the Jacks to react with.
If you read back through this thread there are pages and pages of talk of stock solutions. I personally never had luck with it, but lots do.

When I speak to Krystal Snyder about it, she recommended mixing the stock solution in my well water, and that would stabilize the RO.

I've been using distilled for my raw salt concentrations for the last few batches... I think I'm going back to tap water... I saw some precips using both.... but the plants seem to like it better with the tap for concentrates....

People go ape shit over precips.... To me its not a huge deal...

For those mixing stock solutions with Jacks or any other salt based fertilizer it's normal to see some sediment in the stock solution jug after mixing. The sediment is from the impurities in the salts and not from precipitation.

Fertilizers like Jacks, calcium nitrate, magnesium sulfate, etc are usually 99.5%-99.9% pure. This means if you mix 100 grams of Jacks into a stock solution you should see anywhere from 1/2 gram or less of "impurities" on the bottom after the jug sets for awhile.

I did only use tap, and it was fine for a few weeks, but maybe I'll try distilled and see if I have better luck, thanks.

tap for the stock solution? ive always used ro that starts around 3-4ppm

my tap is clean around 130ppm, I wonder how big of a difference it would make?

After speaking with Krystal I started mixing 450 grams of jacks in a gallon water jug with ro water. 580 grams of calnit in another gallon jug with ro. No more gunk happening or floating around whatsoever. I run 32.5 ml/gallon of jacks and 18 ml/gallon of calnit with 1 gram/epsom in bloom and love it.

Iam using condensation water from my ac instead of distilled water i was buying from stores.I also used standard tap water to make a concentrated mix but with this one iam not doing 10 ml each,i add enough jacks to hit 550ppm and then add calnit to hit 850 ppm.I only make small concentration of tap water at a time as i dont feel comfortable letting it sit with all the stuff that it comes with.

Ever since a year ago the jacks has this foam shit that floats to the top, it's so bad I have to take a fish net and dip it out, i emailed them about it with pics but never got back to me.

I figured they're probably sourcing cheap Chinese material now. But seems to be working as normal
