Making Your Own Nutrient Concentrates

My fingers become numb and tingly when I mix potting soil that has already been watered in with chemical fertilizers (that I mixed myself)... so I'd wager they might live but they won't be as healthy or productive. That's just my honest observation not based on anyone else's findings. Just keepin' it real.
 
Of interesting note and because it was mentioned earlier in this thread... the difference between P2 (phosphorous) and P2O5 (phosphate) is the extra weight added by the addition of the oxygen atom to the phosphorous molecule. Both contain the same amount of phosphorous but one carries the extra weight of the oxygen.

P - 30.974 atomic mass units on the periodic table
O - 15.999 same table

so the mass of a P2 molecule is 30.974 x 2 = 61.948
the mass of the additional O is 15.999 x 5 = 79.995
so the mass of a P2O5 molecule is 61.948 + 79.995 = 141.943

to convert between the two masses
141.943 / 61.948 = 2.2913 so to get from P2 to P2O5 you multiply P2 by that number
61.948 / 141.943 = 0.4364 so to get from P2O5 to P2 you multiply P2O5 by that number

hope this helps clear up any misconceptions.

Sorry... I think one of the other posters had asked a question about that in the beginning of this thread.
 
Hey Sky, hi Diatoma.... I give up. :)

So if you folks enjoy a bit of veg food, check out indian cuisines, were like 1.4 billions folks and bout half are veg.
There is this girl Chetna on the tube, she is like this Indian in the west and does fairly simple home cooking which my (also from the west) wife enjoys a ton.

On the nutes bit, I am not using any sulphates in my A concentrate, only Calcium, NOP, Fe and Mg chelates, so I was quite surprised to see the precipitate.... Of well, the new split into 3 parts seems to be doing just fine so far.

Im now thinking of getting a mild pk booster ready, preflowers started bout a week or so back.
I read that not having a lower N ration compared to P and K can have a substantial negative impact on the quality of the buds ? Is this correct ? And then what would the correct NP ratio be ? Does something like the following make any sense ? A copy of AN BigBud.

Cheers folks!
Take care.
 
As long as your plants are happy I think you should just keep doing what you are doing. When mixing your own nutes you don't need to worry about adding a preflower booster you can just alter the NPK in your fertilizer mix to make any adjustments necessary. You want more P then up the phosphorous in your fertilizer. For off the shelf mixes you would have to settle for a PK booster. Fertilizer is more about soil concentration... what is in the water is what ends up in the soil. Remember that too much of any one element can be toxic to plants so watch for any signs of burn if you up your values. With water soluble nutes you can always just flush them out of the soil with a good watering.
 
Thank you!
So I'm growing DWC (and havin shoddy luck with my first coco attempt). Never managed to grow anything in soil, still can't. Not even lettuce or tomatoes. Need to figure why.

Also I'm trying to keep my nute concentrates numbers minimum, so a max of 3 for regular feeding. This restricts my mix options I think, once im more familiar, I can prolly find a clever combination which can help with different npk profiles. My reason for trying to keep it simple being that 1.Im lazy and 2. I used to travel a lot, and wife would need to tend often, this may or may no longer be the case unfortunately..

So plants I think look healthy, I really have no comparison but pics on forums. Be so kind and pop into my journal too ?

Thanks a super ton Diatomacious

Take care
Cheers!
 
No problem... I must say that Sky's nutrient formulation seems to be right on target... I had ghosting issues at 160 P2O5 in the mix and had to drop back to 150.

I think you use elemental concentrations so 160 * 0.4364 = 69.824
150 * 0.4364 = 65.46
 
I would stay with what you have mixed and keep notes, do research to ensure your suspicions are correct and make formulation adjustments as needed. Also, maybe make a lesser quantity of 3 part so you use it up faster and can make more formulation changes. I estimate that I altered my formulation about 2 dozen times in the last 2 years. Feed for a time and observe, then tweak the formula and do the same again, feed and observe. As far as feeding in soil, if you can get your hands on peat moss, a shit load of perlite and some dolomite, you can make ProMix and just feed your liquid ferts into the pots. The only kicker is that it can't be reused more than about 3-5 times, whereas the DWC rocks are infinitely reusable.

Back in 2001 I grew a strain called super crystal... it had aggressive growth pattern and the bud was very sticky with all the resin the plant produced. You could smoke a bowl in the morning and still be high 6 hours later, great work bud. I ordered some super crystal recently and was extremely disappointed as it was more like a hemp ditch weed.

So my question to any who read this is what is the best strain out there right now for catching a killer buzz?
 
@Norcaliwood has a metric fuckton of life experience and pot, so I bet he will have some insight, but there are so many new strains out there that challenge the 40% THC rpofile that it's hard to keep track of them all.
 
Yea... tons of strains but every one I grow seems about the same as the other... different strains... different seedbanks.

If he doesn't chime in maybe I will message him and ask straight up. I guess I'm fickle but I'm kinda bored with growing weed that barely gets me high... todays stuff just kinda seems like trying to get f'd up off of wine coolers when you are used to drinking Jack Daniels.

You would really enjoy a night with my lungs because for all of my life, 1 puff of anything gets me through the roof stoned. 2 puffs will send me into OD state and I get really paranoid until I pass out. But now, just 1 hit from the bowl will last me 2-4 hours. You should jump on Norcaliwood's thread and post your question to his subbers as Woody sometimes goes days or longer without catching up in his journal. HERE is a link to the last post on his journal. There is a LOT of cannabis wisdom subscribed to his journal and there are many seasoned veterans there.

Edit - there's even a sub that came over from RIU just to sub to Woody's journal, @HydroRed
 
You should really look into eating organic salads and vegetables. Once you find a farmer who grows real organics you will find you are able to breath easier and have higher tolerances (more stamina) than eating chemically grown food. I'm not telling you what to do but this comes from the heart.

I'll jump over there and pop the question when I get a little more time to collect my thoughts later tonight.

I don't believe most of the claims of THC that high. Most are totaling up all the THC compounds. Not just the delta 9

But I do know this,, it takes afew grows of a plant to be able to coax out it's max.. Different soils, food, and even lighting is needed for a strain to be all she can be...

I grow alot from a place called Stoney Girl Garden from here in Portland.. They made claims 9-10 years back of shit getting up in the 30's and everyone said it's BS.. But I seen the test results.


But if you are hitting 40%,, you sure won't be rolling any joints of it........ 40% is hash levels.....

Life good @Skybound ?
 
talking about 2020, here I was just watching this vid


them fools out here are still around.... Not near as much since they started arresting afew of them......

I didn't watch the whole thing... too boring but the difference between 1950 and today is that in 1950 people were more honest... that's it... being nice to each other and God will shine down his blessing upon us once more.

Today people loot and steal like it's second nature. Living off taxation is no better... Christ proved that
