Yes some of the npk ratio it’s says on box or bottle is not completly soluable or available to plant but that is what I base my feeding off as I was not taught to use that calculator to find true ratio/ elementary ratios , I was taught useing the box ingredients ratios / traditional ratios
Would be good to do a side by side to see if it made a difference : )
Then we would also see what the plant likes at certain stages ie what it uses etc , but that’s one more step down the rabit hole than I am prepared to go lol
That calculator would help if mixing mono nutes aswell maybe : )
You could mix up mono nutes easily by just using calculator and ppm meter @GramTorino : )

I used to do the same, and still do as needed.
But, I also realized I could just start with extra water, but add the same amount of nutes. Then after mixing, it’s pre-diuted to the ec you want. May still require minor adjustment until you get it down.
Whipped up a 1.63-1-1 using the 20-20-20 just for practice. Epsom kicker for Mg.

Not trying to drag you into anything uncessary. I hope the recipes (what amounts of what products) to create the desired ratios is of help to some.
I was a ratio dummy. You guys are teaching this old goat about ratios and other methods. much appreciated.
You guys running RDWC - monitoring EC/PH etc - Forgettaboutit. lol
doh - sorry for littering your thread paps.

It’s all good , we’re all in this togeather : )
If it wasn’t for them charts I would never have realised that what it says on box is not what is actually soluable and available to the plant , we all bounce of eachother well , it’s how we move forward in our quest : )

Ok. I think I understand now lol! I was always told that not mixing to full strength would cause me issues because the plants would not get full nutritional value. Bro science I guess. Good to know for sure now that even if I add 1 gram of nutes to a gallon, I still get the same NPK value and ratio, just lower ppm. Wish I knew sooner as it would have made my life a little easier lol! Thanks @Papalag, @ifish, and @GramTorino. You 3 have have made me a better grower.

ALERT: I have zero.zero soil experience.
Feeding soil, I have no idea how this applies.
All I know is feeding coco, inert media, nutes with every feeding.
Especially organic growers, they would never put such filthy chemical salts into their beds!

Even in soil I would feed every watering , say 0.6 ec for example
Rather than 1.8 then water water
Same amount of food for plant but with no risk of root tip burn ( stress etc )
The plant is continually accessing everthng so feed water water is like one step forward two steps back kind of : )
And I wouldn’t water till runoff untill I knew there was sufficent root mass compared to pot size so waterloging was not an issue : )

Jacks I use in soilless at 1/4 teaspoon a gallon every three waterings/feedings
and use plain water on the fourth
outside I use it at teaspoon a gallon every third watering
you can always give a plant more if need be but it can be hard to take it out
all the best

I agree with @dequilo you can always add I never liked to use full strength ,the new ppm meter keeps me in line early stages 400 to 500ish ppm is about 1 teaspoon per gallon
Here’s a few pics
I put up a scrog net in the 24 x 24 tent I set the net at 6 inches above the dirt line I have limited space
The boys are in the little tent set them on 12 / 12
I don’t think I’ll get a female of the banana OG x sour strawberry so I put 2 males in to flower along with the Chuckys Bride pollen chuckin time
I need to switch out the bulbs to the flowering bulbs tomorrow
So thats all for now
Thanks to all who show interest in my work
And thanks to my friends for all there help
Peace

The tray on the left is female for the most part
The 3 larger ones are the petolia pink all ladies
There are very little differences between the 3 the others do look like the they turn out female !
The tray on the right is my hopefully they will turn out female but I know they are boys I’ll give them a few more days to confirm hopefully by Monday I’ll have the final selection for the clones for the 4 Octopots in the big tent
If I don’t get girls from all 5 strains the pp and the CB will double up

Well it’s getting hot in the tent room
So now I have all 3 tents hooked up to my AC infinity t6 fan as intake I split the 6 in vent duct down to 4 in flex ducting with 2 duct splitters making a 3 way connections I turned the fan up to full speed and the force in each tent could blow out a candle
Damn skippy I like this fan

I was thinking of running these out side for my brother in Arizona but thought 
the water would get too hot being 119 in the shade
His plants dry out really fast and he’s killed a few dozen
He just started growing but won’t listen to me about anything
Hell I sent him 60 seeds had he told me all of them didn’t work
So I sent him 100 more damn family lol

Well so far they’ve been in some pretty hot weather mid 90’s and black in the sun I’m sure doesn’t help reflect heat . Still white healthy roots in the bottom but that water does feel warm to touch which I think should be cooler. Wonder if you could bury the tubs or shade them with reflective emergency blankets or a windshield shade to reflect the sun off the tubs.

Thanks bro I think he’s going to dyi self wicking sys
And the windshield shade things around it
I talked him in to a shade cover so we shell see
Hay all look what my daughter gave me a new grinder with a removable screen

Octopots way simpler tho but you might find some nice tips
Heavy reading tho at times on some forums when the experts start talking about that perched water table etc

What’s everyone’s thoughts of adding a bit of hydrogen peroxide to the Octopot mix ?
2 Likes
I found this but not sure how much to add
How Peroxide Works In A Hydroponic System
Generally, hydrogen peroxide is added in small quantities to the central reservoir in your hydroponic system. Once added, here is how it works, in simple words:
- The molecules break down slowly into water and a single Oxygen atom, a free radical.
- This free radical is a very volatile agent, which can react in multiple ways.
- If it comes into contact with an organic cell, like a bacteria or virus, it damages and destroys it.
- If it comes in contact with another oxygen atom, it forms an O2 molecule.
- This molecule is healthy essential for the plant roots.
- The whole peroxide molecule also reacts with any free chlorine in water to form O2 and hydrogen chloride. *
Kills bacteria and viruses, keeps pests away
- Helps fight root rot and fungi
- Improves oxygen content in water
- Stimulates root growth and nutrient uptake
- Removes chlorine from water
- Boosts overall plant growth and health

sounds good
You add mycorizae tho to your soil mix ? , will that not affect it ?
