(Fatman's) DIY nutrient mixing guide

I tried 2ml Micro + 2ml Grow + 2ml Bloom + 0.25g/L ghsc boost and I get.

N 155.33 ppm
P 84.02
K 322.5
Ca 87.36 + Base water not sure but base water ec is 0.15 odd
Mg 91.09
S 101.2
Hydro Buddy says I should have an ec of 1.7 so + base of 0.15 should end up a on the hot side of 1.85ec
I feed a final ec of between 1.5 and 1.65 depending on the temps.

I have a bunch of this brand chem and would like to make the most of it instead of blindly following the recommended mixes so any assistance would be appreciated.
 
Last mix for late flower
5ml/L in 1part g/m/b + 0.1g Ghsc boost + 0.1g mpk gives me

N 128.93
P 78.15
K 271.59
Mg 70.29
Ca 72.51 + 0.15 ec tap water
S 88.6
EC 1.5
This seems like a decent mix and I will be running my next rez with this combo
 
I have access to Ca EDTA at 10% so I could easily up the ca ppm to 92.51ppm with the addition of 0.2g/L.
Not cheap stuff but lasts along time If I use it as a Ca booster.

Mg 70.29
Ca 72.51 + 0.15 ec tap water
S 88.6
EC 1.5
This seems like a decent mix and I will be running my next rez with this combo
If i add an additional 0.3ml/L micro resulting in a 1.66 G +1.96M +1.66B +0.1 boost + 0.1 mpk

The final result is
N 143.16
P 78.5
K 281.94
Mg 70.29
Ca 85.61
S 88.6
EC 1.6

I am partial to this blend for additional Ca reducing the need for Ca EDTA and a bit more N

I will start blending my own or buying much cheaper chem to adjust to taste as I believe this brand Nutriplex ensures higher Ec's than necessary due to the very high S and MG in the bloom and due to the high K in the micro makes mixing a veg blend interesting.....
Just a recap
Gh Grow - 2.1.6 vs NP Grow - 2.5-1-5.5 +0.97 mg all in oxide.
Gh Micro - 5.0.1 Vs NP Micro - 4-0-2.85 +3.6 Ca
Gh Bloom - 0.5.4 vs NP Bloom - 0-4.28-4.87 + 4.9mg0 + 11.5s03
 
Woot! I managed to match the GHSC Hybrid regime pretty closely

GHSC Hybrid 1g/L +1g/L Ca chelate + 0.4g/L boost
150 83 272 56 100(150) 40
Vs
Np 2.5 Micro/L +1.5 Bloom/L +1 Grow/L + 0.1g/L Boost + 0.15g/L mkp
149 83 273 68 109 76
Mg and S are a bit higher and C after tap water is close enough to between the 100-150 ppm
I grow in coco/ perlite 50/50 mix so a bit more mg and s is fine by me.
 
hey guys, new here and dropped in for the good information, i tried actually to contact the initial poster but recon there isnt any option for PM's do they become possible if i am posting more? or how can one get in touch with members here? :) im german living in thailand and due to recent regulation changes cannabis becomes at least legal in medical way while soon it will get further than that, i want to open a fertiliser brand yet probably lacking the knowlege to set climate suiting recepies - @squarepusher how to contact you ? can you write me so i can answer?

I'm finding this thread fascinating. I haven't mixed my own nutrients since my greenhouse days 20 years ago and that was for toms peppers and cukes, so..

Anyway this thread has me teetering on an experiment and I'd like some feedback from those of you running these low P formulas.

I've had good results using the simple floranova line lately because well, I'm lazy.

Based on these results do you guys think I'd do better running floranova grow all the way through flower? Its ratio is 1.75 to 1 to 2.5. ... would it be necessary to bump the Ca/N up a bit? The bloom formula is 4-8-7 and you guys have me seriously questioning using it..

Currently I'm in week 3 of flower, feeding 50/50 grow and bloom at 1.2ec, with another 0.4 ec of massive bloom 1-2-3.
I suspect from reading this that there is a better combination for these nutes.

Any feedback is greatly appreciated.

Haifa is excellent quality. Professional greenhouses use 2-1-2 for general leaf crops. Like Haifa suggests, use a 2-1-3 or 2-1-4 throughout flowering. i.e. Polyfeed GG 16-8-32. Fatman admitted to personally using 2-1-4. They don't mention Calcium or Magnesium ... I hope they're in the formula. Ag is usually very transparent with their numbers, unlike hobby fertilizers (you can't go off their "guaranteed minimum" analysis). hth
 
So I'm trying my figure out a recipe for cloning.... indole-3-butryic acid I can get in g. But there is 1-Naphthaleneacetic acid that I've see. Multiple times in ready made solutions....thoughts suggestions?
