just did my first res. i went a bit over at 0.22g for my 10 gallons. mixed up super easy with just dumping water on top of it. ran my pump for 30 mins and mixed in nutes.
Best way to combat pythium and root rot in all hydroponic growing methods.

I put 3 tablespoons in the dishwasher to clean it and almost killed everyone in the house from the chlorine gas, had to leave the house for a few hours lol.

Nice! I will do mine tomorrow, I only have 5 gallons in my cloner lol! So weighing that out will be fun, might just do the water dilution for that reason then mix that in

And use warm water, it mixes better. I'll be watching this, it's a real mystery to me as to why your not getting this under control. I personally think it's the sprayer setup that leads to bad roots but that's only a theory. I do know a few that have had issues with the sprayer's and abandoned them as I have.

i did have a few moles out in the yard. i put a good scoop in each hole and let the rain that was coming later do the rest. RIP moles.

Just mixed my first shock mix in the cloner, went ahead and cut three clones off the biggest plant since all the foliage was just blocking the other shorter ones anyway, still don't know the sex of anything, if these clones root before I get everything going smoothly (which they will) I'm going to just send the mom upstairs hopefully by then I can get some clones off the other 3 and send those up a week later or so, mixed .17g into my 10 gallons of RO water in my cloner, I had a thought about clones and RO.... Is there anyway the RO water would actually suck the nutrients left in the cutting out of it into the water causing the cutting to become deficient quicker then using say tap or spring water. Just a thought. Anyways the roots on all my new seedlings and the seedlings in general were lookin terrible, while next door at the veg system everything is looking as good as ever.

I really did my best to read this whole topic.
But when that J. Henry started to talk all this nonsense... I felt so sad.
"Plenty of air does not insure plenty of oxygen, air is not oxygen."
Yes, the last part is true, but nonsense anyway. If there is a free flow of air (let's say from outside to the roots of your plants) then there will be always 21% of oxygen in the air. Always. When the roots use some of the oxygen, this oxygen will immediately be replaced.
Only in extreme circumstances (in an explosion, welding, too many people in a small room without ventilation) the oxygen can not be replaced quick enough.
Tell the line "plenty of air does not insure plenty of oxygen" to a firefighter....
Then, getting more DO in your water is useless most of the time. The normal-amount is more then enough, and it is very hard not to get enough DO in your water. Some movement, an airstone > plenty of DO.
Even when water is warm or all the DO has gone, roots still will get their oxygen. Why?
It is true that the cells in the roots can only absorb DO. But that does not mean that this works only when you give them water with enough DO. If pure oxygen (or air with 21%) in some way gets to the roots, and it gets in touch with a wet root, the root will absorb the oxygen. How? The gas-oxygen will dissolve in the thin film of water and turn into DO. And the cells will absorb this.
Oxygen as gas is thousands of times more effective in getting oxygen to your roots then giving them water with enough DO.
This is how plants grow in soil, rockwool, whatever.
That is why commercial growers in greenhouses who grow on rockwool are so concerned that the rockwool keeps an open structure. The oxygen has to get to the roots. The film of water around the roots will do the rest.
In DWC the bubbles created by the airstone are more important for getting gas-oxygen to the roots. Yes, the airstone also insures that gas-oxygen becomes DO. But the bubbles of air around and in between the roots provide lots of gas-oxygen to the roots (to the film of water around the roots actually. The oxygen disolves > DO > absorbed by the cells)
Another proof of this is rice.
Rice grows in water that stands still and is warm. Almost no DO.
Still the rice grows. Why? Oxygen gets to the roots through a tube, similar to a snorkel.
The oxygen (gas) gets in touch with the water around the roots and turns into DO > Bingo.
Oh, and that machine that produces more oxygen (electrolysis) is useless and a waste of money.
Just make sure your roots get enough gas-oxygen, and you are ok.
Always look what commercial growers use, and follow them after it has proven itself.
Perhaps this was all already told in this topic, but again, after 7 pages of blablabla I could not get myself to read any further.

Hay – “Purple Haze”, the classic example of the drug induced logic, hallucinations, meaningless rambling...
Example:
So what DO Saturation is enough in your unscientific opinion?
This is “Oxygen” - https://en.wikipedia.org/wiki/Oxygen
This is “Air” - https://simple.wikipedia.org/wiki/Air
Read this and learn the difference between these 2 gases.
And you really did read further…

Perhaps 1 page further.
I know the difference between air and oxygen.
That does not make your posts less nonsense.
As I wrote (and read it again) air contains for 21% of oxygen. Always.
So where there is air, there is always 21% of oxygen in a free atmosphere.
Always, except in very exceptionel occasions like in an explosion or in a room with no ventilation, and other enviroments when there is no free flow of air, and where a lot of oxygen is consumed, and on the top of Mount Everest.
I can explain it again, but I guess you are so stubbern that you won't read it anyway.
But then perhaps for other people.
Yes, roots can only absorb DO. But that does not mean you have to give your plants water with a high DO level.
It is much simpeler (and more effective) to make sure that oxygen in gas-form can reach your roots.
This is what most growers do when they grow in soil, in cocos, on rockwool, RFX1, etc.
Nobody in his right mind would give plants in such set ups water with a DO of 9 mg/liter.
You can give them water with no DO at all and still the roots would get oxygen.
Because oxygen in gas-form reaches the roots, the roots are wet, the oxygen dissolves in the water around the roots, the cells absorb this Dissolved Oxygen. Job done.
In Hydro it is no difference.
Yes, you can give them water with a temperature around 20 degrees Celsius with a DO of around 9 mg/liter.
This amount of DO you reach easily with even a small waterflow, some movement, an airstone.
But again, it is much easier and more important to make sure that the roots hang in air now and then, or often. (and yes again: I know air is not equal to oxygen, but it contains 21 % oxygen, always)
This is how all commercial growers do it.
It is not wisdom from a book or some weird websites.
Or blablabla from a company that wants to sell an electrolysis machine.
But every now and then someone who does not grow himself, never has been in a greenhouse, but spends a lot of time on the more obscure corners of the World Wide Web, comes around with semi-scientific nonsense.
Millions of growers around the world (and I don't mean weedgrowers) but farmers who grow flowers, vegetables, fruits are doing it wrong but J. Henry knows how to do it rigth.

New Fact: At the top of Mt. Everest
Contrary to popular belief [and misconception] the percentage of oxygen in the air doesn’t change significantly with altitude up to about 85km (52.8 miles) from the earth! http://www.vmeverest09.com/oxygen-at-altitude/

Yes, you are right there.
I had to look that up (so did you)
But it was a very, very small part of my story and not relevant for the explanation at all.
As I see you have nothing else to say that is on topic, perhaps you could go picking on my grammar.
I make a lot of mistakes there as well.

I had terrible luck with chlorine but maybe didn't use enough, my roots were on the verge of death.

what ppm chlorine did you run at? i'm at 4ppm for this grow. plants look great and with hempy buckets, my res temps are pushing 80 during lights on.

Not sure
. I was following a guide here somewhere. The issue I had was not knowing how much was actually still in the water but I guess a pool test kit would have helped lol. I switched to hydroguard and it worked really well, but yes a bit pricey 
. I also chilled the res at the same time .

yeah, i see your point. a plant does use chlorine so it would drop over time. i'm drain to waste so my ppms are constant.Not sure
