Having Problems With Promix Hp

[cowboyz]

So I decided to use promix HP for the first time and been having I problem with it since I got it! I been having pH issues and ppm issues now I just fix my pH to final hit a 6.0 as in the beginning where the runoff it was at 5.2 to 5.4 .now I check the runoff on the ppm its at 1900 ppm plus. So does the ppm on the runoff matter? Or should I flush again or feed it?

And the ppm that is going in is at 400 ppm

I only know about ppm from what I've read around the forums , so let's hope some one experienced stops in.
But if my memory serves me right , runoff ppm has different ranges for different nutrient lines, and isn't promix hp pretty much free of nutrients? What have you added?

4 years and second indoor run

So I decided to use promix HP for the first time and been having I problem with it since I got it! I been having pH issues and ppm issues now I just fix my pH to final hit a 6.0 as in the beginning where the runoff it was at 5.2 to 5.4 .now I check the runoff on the ppm its at 1900 ppm plus. So does the ppm on the runoff matter? Or should I flush again or feed it?

And the ppm that is going in is at 400 ppm

Whoa. To me that says that your medium is loaded with salts. I would flush, but I don't like "hard" flushes, I prefer a "soft" flush and for me that would be using VERY LOW amounts of something like a kelp product, or another one I like is Fox Farms Big Bloom (very low amounts!) to flush. Did I mention to use very low amounts? You don't want plain water, that can be a bit of a shock and possibly cause stress to the plant. Which you don't ever mention, just the numbers. How's the plant looking?

Oh, also, I suggest doing an actual slurry test. Get some 0EC water, measure the pH. Get samples of the media from a few different places, mix them up. Add them to the water, enough to make a slurry. Let that set for 7-10 minutes, then take your pH and EC readings. That should help you figure out a little better what's going on in the root zone.

I think you added an extra zero to those numbers in the quote above.

Dont worry about the PPM coming out of the bag, it wont affect anything.

Top dress with dolomite lime and your PH will never go above 7.0 or add dolomite lime till you reach 6.5 in runoff.

 

[Rootbound]

Feeding at 400 ppm and runoff is 1900 ppm! I would definately worry about that. And when you ph is off in the medium your roots do not take in the nutrients your feeding. Then the leftover nutrients build up as salts in you rootzone. Therefore you need to flush with mild nutrients like SM said.

 

[nightmarecreature]

Ppm close to 2000 in Promix is normal on fresh bags. I had the same thing happen to me and I freaked out. It will go away as you water. Fresh bags do this, my tiny clones are always perfect. Just worry about the PH for now.

Do you mix it in with a watering, or spread the lime on top of the soil itself?

 

[Bogart Tasty]

I use lucky dog but it's the same soilless hydro medium as I understand it. Noticed the same thing, super high ppms on runoff straight out the bag. Seen it upwards of 2-3000 even with straight water. I keep an eye on it each watering but still have yet to see any negative impact from this. ppms seem to stabilize after a couple thorough waterings...

 

[hondo27]

i have same problem the runoff is high ph7.2 from 3rd day i don't know if top dress my buckets are receiving constant water as in air pruned grow buckets with water / nutrient level constant how would i remedy the ph problem while still in midst of grow ?

starting on third day after transplant

 

[sixstring]

So new promix how,3rd day of use and what is your phone going in? Should be around 6.0 to 6.2 and if it is don't worry about runoff for now.promix has pH buffers, you'll be fine.

 

[hondo27]

Thanks for rapid reply i noticed it on third day but has been running problem of after ph 5.5 to ph 6.0 morning runoff is at ph 7.2 i see now it should be tested and adjusted prior to use ...late knowledge and hindsight will know better in future but would be great to correct it in use without plant shock

 

[hondo27]

am on 3rd week of veg now but daily monitoring is must
