DIY Hydroponic Nutrients in 5 minutes

[klx]

@churchhaze or anyone else care to take a look at the attached recipes and give any feedback? Made up of a commercial NPK + trace element mix, calcium nitrate, magnesium sulphate and additional Fe chelate edta.

Cheers.

great thread

have most water soluble horticultural/ elemental ferts to mix my own, currently only using as additives to my generic base nutes as i still need to source micros.

my question is on Mono Ammonium Phosphate (map) for hydroponics eg not soil, now as far as my research goes 10% Ammonium of total nitrogen in solution in hydroponic grows is fine, has anyone used more used more than 10% and had issues? ( if growing in hydroponics, not SOIL )

just trying to find ways to increase p with out pushing k up

thanks

Helpful thanks!

I hydro, you can use potassium phosphate (MPK) which is almost the same ratio of p and k. Your plants don't ever need more p than k so you can simply limit the other sources of K. I use phosphoric acid as ph down so it adds P as well. I only use a small dose of ammonium nitrate as an N booster in the veg stage. I didn't see the benefit of adding ammonium and phosphorus when i can add PK at a similar ratio. I find myself always needing some more K. In flowering late stage, i would aim at 1-3-4 or so i get the added k from potassium nitrate and potassium sulfate

I hydro,

Hey zem,
yeah i do agree in general, i mainly just want to experiment really, that's why mixing up your own nutrients from scratch can be so useful , from seedling to early veg for root development and just for the transition period.

currently using a store bought dry premix with micros at 4.5-1-5.5 and i'm in early veg, so as p seems a little low in the ratio i figure up it to a to a 5.5-2-5.5 / 6-2.5-5.5 and experiment with map for more vigor as p also promotes energy in plants.
i'm also using fulvic acid as a ph down, so with such a low p value there's no extra p from ph-ing, sure is a bit of added potassium with the ph up.

so your dose of ammonium nitrate is from your calcium nitrate or are you using straight ammonium nitrate salts?

It is ammonium nitrate salts. in some cases the sale of it is banned even in small quantities so you can get calcium-ammonium nitrate. I also replace magnesium sulfate with magnesium nitrate if i want a higher N. I don't recall a lot about high p low k salts since i never used them, look up something called triple super phophate and others. and check their solubility and general properties. i think it had calcium and phosphate in it.

Thank you again chuchhaze, I know that you have be gone for a while but here is a proof that your shit works. I use RO water so I also make my own cal mag plus (I know you hate cal mag )

I tried my mix in coco but I had K toxicity

ps. You forgot to mention hydrobuddy works on windows 64 bit (x64)

thanks again and happy growing

I'm going to start experimenting with @churchhaze recipe. I also have hard water and would actually enjoy using it instead of making RO (which I can do). I'll be in Coco perlite mix. When you say you had K toxicity, what happened?

 

[Dan_J]

does anyone know how much micro nutes to add with your a+b solution ?
will be getting around to trying my own batch of npk as i can find hydro micro's in a all in one dry solution mix.

so my question is if my a+b solution is say 200ppm are my micro's to be say 10ppm?
so i up to 400ppm would my micro's be 20ppm etc ?
thanks

To be real I was running my moms for the first time in straight coco and using 202 Of K, they didn’t like it at all. Also I was overwatering. After years of growing on and off you learn most of the common plant deficiencies. I’m no pro with coco so most likely it was user error plus high K.
i read somewhere, sorry I don’t recall where exactly it was but for coco 135 -150 of K. I tried 202 and I fucked up real bad. These plants are the clones that I luckily save from them. I went back to aero/nft where I have most of my good experience growing.
Happy growing

If you are already playing around with hydrobuddy, I been using this numbers circle in red as my main micros in a B concentration.
In A only goes calcium nitrate, Iron and potassium nitrate or maybe another nitrate.
I only have had calcium deficiency because I was running 100ppm of cal mag and RO water, bump it up to 150ppm@700 problem solve no more deficiencies at all in my aero set up thank god lol.
I hope it helps.

Reading and learning.


This is my current coco recipe.

Feeding at 1.8ec. 6.1ish

Untested...
Jacks 10-30-20 recipe using tm-7 for micros.

Also check out side wing post about hydrobuddy, but use the concentration at 400
which it translate to10mL a gallon
Good luck.

So if you've ever been interested in creating an exact nutrient profile and breaking free from the money pit that hydro companies are, hopefully this will be of some use. Don't know if this is the right place for this, but I thought a thread on how to use hydrobuddy where anyone can input their...

@TintEastwood @Mont@n@

Do you guys tried 230-250 ppm K in coco/perlite DTW? Any troubles?

I am curently running at 200 ppm K, but don't see any problems. Now I found new cheap nutrients, but I am little worried about that much total K.

 

[Mont@n@]

Don’t worry, it looks like Tint it using 200k with no problems. Also take in count it was my first experience with coco, theres a lot of things that can go wrong and apparently that happened to me. I was just trying to avoid using a pump hydro system set up in my moms room due to hurricane season but I fail real bad. Also I was going through a divorce so that might influence a lot on user error.

I’m out guys hopefully you can pass the info to other growers of how easy is to make your own nutrients and please keep this thread a live for discussion.

good luck everyone
Ps don’t use clear bottles like me.

@Mont@n@
great thanks, that will keep me on the right track.
seems to be a+b at 633ppm with micros at 5ppm which would be 10ppm at 1200-1300ppm of a+b?

I wish I could help you but right now I don’t have a pc that could run hydrobbudy to run your numbers.
Good luck

Many thanks to all of you. Spent the last week reading as much as I could and ordering supplies. Does my 1st recipe look okay?
Will be doing Coco/Perlite drain to waste.

I have been using jacks 5-12-26 at the 3-2-1 ratio but now i am using 3grms-2.5grm (cal-nit) and no epson salts. If there is a mag issue, just add a bit epson. Also mkp at .5grm at week 3 of flower. Fulvic acid throughout. The K and calcium is higher but they are liking it.

 

[DoobieDoobs]

Man this thread is great, I want to do things the organic way (I already got my soil mix prepared for the next grow), but if I were to use more bottled nutrients this is the way to go for sure. I was using AN nutrients pH perfect and it was a great grow, but I was thinking about this at the time, making my own nutrients. Good work guys!
