HELP - DIY Nutrients

[ifoodhippie]

Hey guys, starting my cannabis hydroponics setup in AutoPots this week and I have a couple questions regarding nutrients that I'll be mixing at home.

My mixes would be either:

Component g/10 L
MKP 2.336
NitCal 6.667
Mag Sulfate 5.816
Potassium Sulfate 2.795
Sodium Molybdate 0.005
6% Iron Chelate EDDHA 0.50
Copper Sulfate 0.006
Manganese Sulfate 0.016
Zinc Sulfate 0.008
Borax 0.029
Mag Nitrate 3.818

Results in PPM mixing with 1lt RO water

Nute PPM
N (NIO3-) 154 ppm
N (NH4+) 0 ppm
P 52 ppm
K 180 ppm
Mg 87 ppm
Ca 120 ppm
S 103 ppm
Fe 3 ppm
Mn 0.50 ppm
Zn 0,149 ppm
B 0.50 ppm
Cu 0.15 ppm
Mo 0.19 ppm
Total PPM 849 ppm
EC 1.805 mS/cm

OR simply

NitCal, MKP, Micronutrients MIX, Mag Sulfate, Potassium Sulfate
This would not be the perfect mix because of obvious reasons, I don't have little parts of every micronutrient to mix.

By Micronutrients MIX I have 2 options, which I prefer the first one because the other has N in it..

1st: B 0,85%, Cu 0,5%, Fe 3,4%, Mg 1,2%, Mn 3,2%, Mo 0,06%, Zn 4,2%
2nd: N 4%, B 0,70%, Cu 0,2%, Fe 7%, Mg 0%, Mn 3,30%, Mo 0%, Zn 0,6%

1 - Do I really need to make A + B concentrated mixes or can I just mix all together in the reservoir? If so, what can I separate into A and B?
2 - Is it ok to mix both Mag Nit and Mag Sul together? I was having difficulties dropping S from 140+ while maintaining Mg in desired levels.
3 - Do I need an airpump running on the reservoir? If so, how long per day?
4 - What can I do to keep the rez clean? Is adding Hydrogen Peroxide (H2O2) safe and efficient?
5 - Is this mix OK for vegetative stage? I plan starting in seedlings with 350-450 ppm and then get to 800 week by week as the plants grow bigger. I still have to plan my nutes for flowering stage, by reducing N and increasing P.
6 - Is the ratio 1.2:0.8 good for CalMag?

Sorry for the long text guys, I just wanna start the right way hehe

If you have suggestions, I'm all ears (or eyes in this case)!

Why not copy some of the tried and true formulas like Jacks 5-12-26 or 0-12-24? I would leave Calcium nitrate as a second part, then you can create a two part stock solution for easier mixing and operation.

PM if you need any common recipes and copies on common formulas, I have a couple calculated and written down.

Cheers!

Hey, Wastei!

Yes, thats exactly what I'm trying to do: copy Jack's Part A + B as a generic formula, they're well known and people always indicate and tell good things about it.

Will for sure PM you!

6 - Is the ratio 1.2:0.8 good for CalMag?

I remember reading a paper by UC Berkley that recommended K:Ca:Mg be supplied at a rate of 4:2:1

So, you should be able to drop your CalMag to 90ppm:45ppm
Sulphur is non-antagonistic and anything over 50ppm is fine.
