Many experienced folks around here. They may be able to chime in on discussions about creating your nutes from raw salts. alot of folks takd that route. I give my money to gh lol.

Wow, what a ton of work. Just harvested recently. Good first hydro grow. Still cleaning the room. Four pounds, 11 plants, no issues except for the learning curve mistakes. Initial investment more than balanced. I used a 30% THC, OG Kush blended strain from England; 75/25 Indica/Sativa. Seems like a winner, now just waiting on the cure. Clone girls already to go. I figure two weeks in veg., then time for the stretch. No rush this time. It's amazing. I feel like there are tomes of information to digest, yet I have assimilated a gluttony. A few modifications and some adaptations for the season, I foresee 25% increase, minimally. I'm going to utilize two tents; more space, and automate pH adjustments. I have acquired some PGR's, and combined with the monster cropped clones, I think an attempt at a SCROG will yield some nice colas. I sure would like some thoughts on nutrient optimization, but I have only found the older threads. If there are any giants still out there with knowledge of raw salt nutrient mixing, or anyone who knows of a good thread, I'd sure be pleased to hear from you.

everything in the entire world you could ever dream of about mixing custom nutes, one of the single most educational and informational threads I have ever read

Oooh I have a nerdy thing for you to check.
I have changed my hydro nutes, it comes in 3 packs, each you make a concentrate of, and then add to water according to a schedule.

Nutrient A Contains:

Nitrogen N 66g/kg
Phosphorus P 45g/kg
Potassium K 239g/kg
Magnesium Mg 45g/kg
Sulphur S 71g/kg

Trace Elements:
Iron Fe 1700 mg/kg
Manganese Mn 400mg/kg
Boron B 500mg/kg
Zinc Zn 200mg/kg
Molybdenum Mo 50mg/kg
Copper (Cu) 30mg/kg

525g makes 5l of Concentrated Nutrient Solution.

Nutrient B Contains:

Nitrogen N 155g/kg
Calcium Ca 190g/kg

350g makes 5l of Concentrated Nutrient Solution

MPK Contains:

Phosphorus P 227g/kg
Potassium K 286g/kg
Then there is a table for mixing it.

125g makes 5l

Part A Part B MPK ml per liter
1ml 1ml 0ml Week 1
6 8 2 Week 8
11 16 5 Week 16

There is a dosage for every week, I just selected 3 nodes.

Do you see anything that looks counter productive?

Result so far are OK. Cost for the kit, about $7

Hey, sorry about the reprieve. I do not see the juxtaposition here. I do mix nutes from raw salts and and other ions, but also incorporate flora to balance the bioburden. I have found that increased absorption of required nutrients is optimal with a hydro/aeroponic system, but it needs to be fortified with a balanced microbial flora to deter the pathogenic organisms. Maintaining sterility is a fallacy; a western medicine myth. Ergo, I utilize hybridized methods. If, on the other hand, you are referring to the usage of organic nutrients, e.g., urea, I only foliar those in conjunction with hard to move, or deficient elements- with or without the addition of surfactants or hydroscopics. Therefor those carbon based "organic" nutrients never enter the reservoir, and do not influence the microbial ecosystem. I hope this answers your query, but if not elaborate further so that I might explain my reasoning.

You aren't growing with microbes when you use fertilizer salts, it's the exact opposite of microbe farming. You should read teaming with microbes since your such a pro microbiologist.

Hey ANC, sorry this reply is so late. I was on holiday when you posted and well, life, work, women... So, I skimmed over your nutrient profile and it looks good, especially for the cost. I did not see a few nutrients, that I might add. If you are using R.O./distilled water to constitute the solution, you may have to add a few things. I don't see any Chlorine or Sodium, a few grains of table salt would suffice, but check the packets they might be in there. You might also consider a Potassium Silicate addition. The KSiO4 does not like others, so dissolve prior to addition, and add it last. I didn't scrutinize the formula, nor apply maths, so these are just suggestions.
HTH,

Yodaweed!
Hey there, I have read many of your posts while searching the forums. Thank you for the observations, I reread my post, and I was obscure in some of my statements. You are correct, I'm not growing with microbes for the most part, although the fungi can interact in a synergistic, or mutualistic, relationship with the roots to increase absorption. The bacterial flora that I incorporate act merely as competition to the pathogenic bacteria. They limit the system resources to modify and reduce the proliferation of pathogens. In soil they could have additional benefits such as nitrogen fixation, urea reduction, liberation of phosphorus and mobilization of minerals, but that is not going to happen in hydro. I hope this clarifies my previous statements, and it's great to have your input!

Thanks,

Sounds very interesting. Thank you for all the info. Could you post some pics of your working area and plants. Would love to see your results. Again thank you

Hi Leather lungs,
I just got interested in high pressure aeroponics and don't have pics of a working system atm. So I'm creating the new system at this point. I did post a pic of the three OG Kush seedlings that just popped in this thread; https://www.rollitup.org/t/high-pressure-aeroponics.956723/ . I'll update that thread as I go along. So far I just have the seedlings, I'll have to clone them before they are introduced to my new project and I'll post progress as I go. Thanks!
