2. The pH Rule :
There are separate pH rules for RO and tap water.
We will discuss RO first.
With RO, you will control the buffers.
There are three chemicals
that will allow you to get a stablized nute solution
without causing any nutrient lockout.
First you need to get some AN Barricade
which is Potassium Silicate.
You should also get some Potassium Carbonate,
and Potassium Hydroxide.
I buy these two chemicals premixed
in the powdered form from GH,
and then add RO to make a solution,
which I use to increase the pH with my eye dropper.
So here is the drill.
Add the nutes and any additives you are using,
and then measure the pH. (do not add Barricade until the pH falls below 5.6)
Most of the time the ph will be around 5.6
right after you add the nutes.
In a few hours check the pH
and it will be down as the buffer is overcome.
(I let it go down until 5.2-5.4
and then add Barricade to bring the pH up to 5.6).
Add one drop of barricade per gl,
and then check the pH.
( you need an eyedropper)
Keep using Barricade to bring the pH back to 5.6
until you have reached the max dose of .5ml/gl
(5 drops/gl of barricade max)
After you have maxed out the barricade,
then the next time the pH falls,
start using the GH Potassium Carbonate/Hydroxide powder in RO solution,
to bring the pH back up to 5.6
and after a couple of days the pH will stop moving.
You will have the solution buffered
with these three potassium molecules
and can reach a perfectly stable equilibrium.
When you add nutes to RO water, the nutes alone will probably lower the ph to around 5.6
If the ph drops below 5.6 after you have added new nutes to RO water,
use .1ml/gl Barricade to buffer the ph back up to 5.6.
Solutions with RO or distilled water
will require the use of an eye dropper to maintain pH.
Measure pH between each drop,
until you are familiar with your solutions requirements.
seriously answers are out there but...
(sorry if Im spaming a bit)
TB how do you do it?..
