(Fatman's) DIY nutrient mixing guide

[Crysmatic]

if we can make our own nutes for dollars per gallon why not start with the 'ultra premium' formula? (connoisseur is $190/4L). i'm shocked that a 500g tub of bud blood sells for $274, for literally $10 worth of material :O i'm also shocked at the density of conn...FNB is 1.51 g/ml, conn is 1.025 g/ml...it's practically water!

using AN's calculator: conn runs weeks 1-7, big bud weeks 2-5, b-52 weeks 3-7, overdrive week 6-7. this 8 week cycle will cost $226.36 +tax, assuming a 100L res. diy should cost around $15.

i used pH's spreadsheet to calculate ppm based on the suggested application rates (4 ml/L for conn, 2 ml/L big bud, B-52 and overdrive).

total ppm, NPK ppm, overall NPK ratio
week 1: 960ppm 274-91-339, 6.7-5.1-10.0
week 2: 1040ppm 274-101-394, 6.7-5.6-11.6
week 3-5: 1120ppm 337-156-533, 8.2-8.7-15.7
week 6-7: 1040ppm 359-194-551, 8.7-10.9-16.2
week 8: flush

normalised for P overall NPK
week 1: 1.3-1-2.0
week 2: 1.2-1-2.1
week 3-5: 0.94-1-1.8
week 6-7: 0.8-1-1.5

if you ignore b-52, you have the same formula from week 1-5.

weeks 1-5: 274-108-425
calcium nitrate 574g
potassium nitrate 300g

epsom salt 300g
potassium phosphate 190g
standard fatman micros
4L 100x stock solutions

this is equal to connoisseur plus big bud. note that calcium went from 74 ppm to 243 ppm. calcium is 89% of nitrogen.

weeks 6-7: 297-139-413

ammonium nitrate 154g
calcium nitrate 531g
potassium nitrate 247g
potassium phosphate 244g

this is equal to connoisseur plus overdrive. i used 10% ammonium nitrate to keep calcium from reaching 300 ppm (it's 225 ppm).

So, is there anyone else on this or any other site that can teach me how to make my own nutes? I am appalled that Fatman was banned because he is a "dick". If you don't like what is on the TV you change the channel.... NOT GET THE SHOW TAKEN OFF THE AIR!! I wonder how much the nute companies are paying the mods on this site?

 

[MeJuana]

What you said about fatman is true, if you don't like what he is saying change the channel. But if you own the site banning him is changing the channel, this site goes out of it's way to help people and if the owners get a little pay that is great.

No one can teach you how to mix your own nutrients. You have to have enough honest interest to start studying and then practice makes perfect is what I am hoping. Can you order exactly what the other guys did and follow their instructions if they were nice enough to list them?? No I am wondering if you can even do that.. :P Coming on a site and having that be one of 4 posts, doesn't give me a lot of hope for you especially since the admins here are known and you can sack up and PM war with them directly AND this wasn't even the thread he was banned from, we are followers we probably all would rather have him. We don't own this site.

Crysmatic that is awesome thank you again. This is exactly the kind of thing I wanna toy with too and yeah man the prices are stupid.

i realised that 100x concentrate is fine; it's 5 ml/L a+b, which is comparable to AN sensi at 4 ml/L. second, the copper sulphate doesn't fully dissolve. the iron eddha has a little precipitation, but the dpta may solve that (but i paid $60 for 1 lb eddha, so i'm using it dammit). eddha also makes part a look like blood! 65 ml each part a and b in 20L tap water (0.34 mS) gives me about 1.0 mS.

my cuttings seem to love this formula. over a few days they doubled in size.

the AN recipe above is for RO water, and DTW. I can't post an exact copy of the AN recipe, because they use urea (to get the calcium levels so low). urea isn't useful or recommended for hydroponics. it's designed to work in soil with beneficials.

check out the allhydroponics blog, he teaches how to make noots there

I bought the iron dpta (I think it was 7%) because they were out of the edta 13%

No precipitation from the iron dpta at all.

sadly I do have a greasy residue from the calcium nitrate. I am using yara live 15.5-0-0, which is a double salt calcium nitrate. From what I've read...the pellets are coated with a waxy resin. It actually is made for soil so that it does not leach into the ground at too fast a rate. If it is only a coating made for slow dispersal...I think you could allow the precipitate of the coating to sink to the bottom and them pour off the remainder. Not sure though...just a thought

 

[Crysmatic]

good to know about the dpta and yara.

i would stay away from all slow release ferts...how do you know what's being released, or what's in solution? yara also has ammonia. if there's going to be a chemical in my solution, i want it to be there because i put it there, and in the exact amount i want. my .02

 

[budboy299]

which calcium nitrate did you go with Crysmatic? I may end up switching over

 

[Seamaiden]

You guys seen this downloadable nutrient calculator by Fernandez right? Man I feel so well armed with it, I haven't had a lot of time to play with it yet but it is awesome. Gives warnings for bad mixes too!

Fuck, it's an executable file, and I don't know that I have dot wine installed (probably, but still). You wouldn't happen to know if there's a Linux build for this, wouldja?



****Edit: Have it running on Ubuntu... Karmic Koala I think, just using wine. Rough GUI, but if it functions and I can read it, who cares?****

 

[budboy299]

Just noticed that the calcium nitrate I got (was supposed to be greenhouse grade) was actually slow release as crysmatic mentioned. It said tropicote on the side, so I phoned and the supply co. admitted it was a mix up on their part. Whew!

i run hydro buddy straight in linux, seamaiden. i didn't do anything special. just downloaded, unzipped, and ran the program :)

bud: hydro buddy includes yara brand. connie + big bud:

potassium nitrate 300g
yara calcium nitrate 442g

magnesium sulphate 300g
potassium phosphate 190g
plus fatman micros
100x 4L
pH 6.05 3.72 mS

actual npk-ca-mg ppm 275-108-425-210-74. connie + big bud actually has 72-41 ppm ca-mg.

connie + overdrive:

ammonium nitrate 109g
potassium nitrate 247g
yara calcium nitrate 448g

magnesium sulphate 300g
potassium phosphate 244g
plus fatman micros
100x 4L
pH 5.94 4.0 mS

actual npk-ca-mg ppm 297-139-413-213-74 with 10% ammonia. connie+overdrive actually has 70-62 ppm ca-mg.

or

potassium nitrate 247g
yara calcium nitrate 545g

npk-ca-mg ppm 297-139-413-259-74.

i messed up in post #81 for the AN recipes and i can't edit it:( here's a better version. i make no warranties for performance.

i use DNF straight calcium nitrate, which is 11.8-0-0.

connie + big bud:

potassium nitrate 300g
yara calcium nitrate 578g

magnesium sulphate 300g
potassium phosphate 190g
plus fatman micros
100x 4L
pH 6.05 3.94 mS

actual npk-ca-mg ppm 275-108-425-244-74. connie + big bud actually has 72-41 ppm ca-mg. you could probably run this all through flower, and you don't have to buy ammonium nitrate.

connie + overdrive:

ammonium nitrate 172g
potassium nitrate 247g
yara calcium nitrate 511g

magnesium sulphate 300g
potassium phosphate 244g
plus fatman micros
100x 4L
pH 5.94 4.01 mS

actual npk-ca-mg ppm 297-139-413-216-74 with 30ppm ammonium.

Crysmatic, yep, I figure it out finally. Just clicky, just like Windows! I just have no idea what I'm doing with this thing. I feel like I'm in the cockpit of an F-16.

On the connie there seems to be missing some salts.

 

[kuz]

I see only 1.7% ca in the connoisseur? Npk-mg-ca, 4ml A &B and 2 ml big bud per liter.
Connie; PPM: 268-98-381-40-68
Sensi; PPm: 200-97-381-208-28
NPK without big bud;
Connie; PPM 268-90-332
Sensi; PPM 200-88-332

 

[MeJuana]

I wanted to see what is inside the Super Nutrients SBA and SBB that I have. So I searched for that webpage that fatman mentioned where people have to have the guaranteed analysis or that can't sell in certain states. Is this the right one?

salts missing from AN's ingredient list? or salts missing from the diy recipe?

Connie; PPM: 268-98-381-40-68

NPK without big bud;
Connie; PPM 268-90-332
Sensi; PPM 200-88-332

you're closer than i was. connie's density is 1.025 g/ml and big bud is 1.1 g/ml. it gives 275-101-395-70-41.

companies make incomplete formulas so you have to buy multiple products...the calcium is in their calmag...and so is nitrogen, which throws off the NPK ratio.

this is the one you're looking for.

Crysmatic, I'm sitting here doing a comparison of both sites, and the WA site is incomplete in its listings. For instance, try finding the manufacturer "Advanced Nutrients". I can't find them on the WA list, but I can on the CDFA list. Perhaps it would be better to make use of both.

i just took a look. it seems like they went to AN's site and copied the NPK, and forgot calcium and magnesium. it's strange that AN hides their micro ppm, when it's within a couple ppm of any other major fertilizer. h&g doesn't even post NPK on their site...

imo, you don't need more than NPK-CaMg to copy a fertilizer. your micros will be proportional to calcium. higher respiration (lower rH and higher temp) needs more K. Ca should be 0.8-1.0 of N. 3-1-2 for veg, 2-2-5 for bloom. i'll keep searching for other rules of thumb for *designing* nutes.

as far as other sites go, i'm sure washington state isn't the only one that analyzes fertilizer.

fwiw, botanicare power plant is 3-1-4 and power flower is 2-2-5. a quick check on the washington site shows it has more heavy metals than i'm comfortable with. diy with pure salts at least has the potential to be cleaner.
