Yea, me too. The only thing I can think of is that it's sitting stagnant and getting circulated in any way. I'm going to try and put a pump in there to give some movement and let a fresh rez sit for a week and see if that does anything. I'll keep ya posted.
...
Also, when one mixes a reservoir of standing solution, is fallout more likely? I've had a bucket of nutrient solution sitting around for longer than usual (probably 5-6 days) and there's a bunch of brown on the bottom now. There's no water movement or aeration at all in this bucket. Just some nute soup.
From JR Peters on the phone this morning... they're going to be releasing a HydroHerb Flowering formula later this summer. :)

I prefer a circulation pump in the rez. IME they work better than airstones.
I would guess if its brown it may be the iron settling... but that is a wild guess. The only sediment I have ever noticed is a few grains from the jacks hydro that will never quite dissolve.
So I did a little more research into it and one of my plants definitely looks like it's deficient in iron. It's my last DWC plant that I've got running. Started phasing out the DWC 6 weeks ago. Everything else is in promix now.
So, it totally could be iron falling out, but not sure why. Thanks for the heads up on that, cap.
iron could be dropping out due to a change in pH, all depending on how it's chelated.
Here's what the bottom of my bucket looks like after 12 days. it's definitely brown. This is with RO water and adding nutes just as one is supposed to.

52.8 X ? = 7.8 X 1
?= 0.1477
14.77 grams of 52.8% AgSil in one liter final volume gives you a solution with 7.8% SiO2

Quantrill - just getting the hang of all of this. You add the 14.77 grams to a liter because grams per liter IS ppm, correct?
Agsil16h label says:
This is a 1.6 weight ratio hydrous potassium silicate powder with 32% K20 and 52.8% SiO2 and 14.8% H2O.
.7 grams in one gallon of water yeilds 98ppm SiO2 or 46ppm Si, and 49ppm K.
And the Protekt label says:
Product Analysis: 3.7%* potassium (K2O), 7.8% Silicon (SIO2) [dont know what the asterisk after the potassium is about]
The same site as above also says (if they have their math correct):
Dyna-Gro Pro-Tekt is a concentrated solution of Potassium Silicate. With 3% K2O and 7.8% SiO2. One mL per gallon yields 8ppm Potassium and 21ppm SiO2.
