how does my grow flow

i have some experience with mixing dry nutrients. i have used jacks pro hydro and mag sulphate to make an A concentrate and calcium nitrate to make a B. i have never been able to get it completely dialed in though.

i appreciate all the info you threw up. i am probably going to order some 4lb containers off of customhydronutrients.com and see if i can duplicate whats been working so well for you. for smaller grows general hydro has been working great for me, but we are getting ready to have some moderate sized greenhouse grows and need to get a dry nutrient salt recipe dialed in.

looking at a close up of just this section of the veg, at the top it says reservoir volume that's 4000 gallans, that's the total amount the concentrate will make

so I add
6800 grams of calcium nitrate
2000 grams of potassium nitrate
4000 grams of magnesium nitrate
and the iron

to the 5 gallon bucket labeled "veg A" of warm or hot water filled about 2/3 full with water leaving room to stir

after adding each 1 at a time allowing most of it to dissolve before adding the next
after its all in I top the bucket off to the rim

do the same thing to bucket "veg B" adding all the others = potassium phosphate, magnesium sulfate potassium sulfate and all the micros except iron

the formula I use is very close to what general hydro 3 part puts out

except my formula adds for what theres is lacking which requires the addition of cal/mag and or extra Epsom salt

if you have hard tap/well water ph 8.0 you may not need as much Ca

I use Hydrogardens.com as my dry nutrient supplier. They're in Colorado which makes it convenient for me.

I use their 'hi K' hydroponic formula,
5-12-26 with micronutrients.

I also bought Yara Liva brand calcium nitrate from them as the complement.

I use epsom salt, aka magnesium sulfate.

In bloom I add a bit of MKP. That's everything I use in the res, full stop.

All numbers are in grams, per gallon of nutrient solution:
Veg;
3g calcium nitrate
2g 5-12-26 mix
1g epsom salt

Bloom;
2g calcium nitrate
2g 5-12-26 mix
1.5g epsom salt

I'm not sure how these numbers compare to yours?

I'm also interested in hearing more about your automated nutrient dosing system!

I can run the numbers if you like

I will get back to you

veg

flower

this does not give full account of your calcium or magnesium since I don't know what amount of each is in your 5-12-26 mix

what ever type of system you run might drastically change what works best for each person

deep water culture dwc has different needs

and if I was growing in coco it would also be different again

personally for me... in my set up... your flower mix would look great for what I would use for veg

but that's me.. there are other factors, water source for example

in my opinion for what its worth

the calcium is very high in you veg mix and so is the nitrogen... unless your in soil maybe

when I started I didn't mix concentrates.. instead I would do a direct addition

so I would just measure the grams for each and dump them directly into the res

its difficult to do with a small res ... I recommend at least 100 gallons or more

but I used peters s.t.e.m. which is a micro nutrient mix

so I didn't need to measure each micro nutrient individually which is hard to do in such small increments and requires a scale that measures micrograms or whatever

the peters stem is sold by the same place... the shipping is what you want it to be

the peters stem I find that 0.9 grams per gallon is good.... I have seen others recommend 1.0 grams per gallon also

it makes it easy to do and would allow you to test things out and see what works best for your set up before investing/committing to mixing 4000 gallons of solution into 5 gallons of concentrate

in my case what I use to blend my nutrients I can set the ratio to a lower P but to do so I have to use more potassium sulfate to raise the K back up to range after the reduction of mono potassium phosphate reduction required to lower P

the increase in potassium sulfate throws the sulfur way up... so im trading either P or S

I tried it both ways and in my opinion the high sulfur affect the taste negatively and the low P made for softer buds

I'm in RDWC. Thank you for the analysis!

The plants absolutely love it, and were not as happy with only two grams per gallon of calcium nitrate.

How would you adjust my bloom formula?
