where am i supposed to get all those chemicals, its easier to just buy it from the store. I thought this was gonna be a homemade organic fertilizer thread.

calcium nitrate

you'll notice the label reads 15.5-0-0 it is also 19.0 calcium.

talk about fast green up and veg growth.

this brand is "greenhouse grade", which means it goes instantly into solution and won't clog injectors.

potash and epsom i should mention that the rite-aid brand mag sulfate is 4.99 for 6 lbs and is the only epsom salt that i have found goes instantly into solution

phenotypex, everything you see was purchased within 50 miles of my house at ag supplies and garden centers.

that's a 50lb bag of cal-nit
2 25 lb bags of jacks
6 lbs mag-sulfate
and everything else you see for less than $175 US

try buying 115 lbs plus of concentrated greenhouse grade nutes at the grow store for that. they won't even have it because they are making way too much money off our sore asses with the stuff they sell. they do not want you to know about this. next time you go into one ask them for jacks or greenhouse grade cal-nit. get ready to laugh your ass off at the bs you will hear. not cannabis specific, etc. these are actively being used daily by greenhouse professionals growing every plant you can imagine. these people are not going to use crap as they are making their living from growing.

it's the same with turface. 50 lbs for 10bucks at turf suppliers. they won't even talk about it at grow stores as they don't sell it. they will, however, be happy to show you a badly overpriced bag of hydroton, which is the same basic substance in a different form.

back to your "making your own raw salt fertilizers". you can do it. you will have to find individual sources for most high grade chemicals. order them in large bulk quantities so large you won't use them the rest of your life. pay individual shipping. need an expensive precision lab grade scale. have a strong chemical background to keep from fucking up, and so on.

the reason ag professionals use somewhat pre-mixed salt packages is that they are already pre-mixed in ratios for specific crops at extremely reasonable prices. both jacks and total-gro.com sell huge amounts to professional growers, there has got to be a really good reason as they make their living from it.

www.totalgro.com is an excellent learning site. loads of information. they used to offer a 55 page pdf tutorial free online in it's entirety. it's still free but they have taken the link off their site and want you to order it. i'm sure salesmen will contact you. any way, ive got the document saved if anyone wants to see it. be forewarned, it's 55 pages. i'm not sure it's ok to take up that kind of space here.

in the face of all this there are some really valid reasons for someone in our hobby to mix their own for experimental purposes. plant researchers take complete raw salt ferts combos they have mixed themselves and start growing a specific group of the same plant with it. when all is well and good they start eliminating specific salts to see the symptoms and effects of deficiencies. this has been done with almost every valuable plant in the world except for cannabis. while stitches nutrient deficiency sticky is excellent. it was not put together using these methods, which i feel would be a great way to take all the guess work out of diagnostics for us.

also, i don't see a single reference to "homemade organic fertilizers" except for yours. this is a raw salt mixing thread, i think.

that 55 page document should be somewhere in the nutrients & fertilizers forum...

kbs/freedom bucket threads had 15-20 pages dedicated just to air pumps & soaker hoses!

excellent post!
paraphrased from growing edge, vol 2...:

the base steiner formula, consisting of two 4 liter stock solutions

stock solution part 1
calcium nitrate (15.5% n, 19% ca) @ 364.9 g (12.9 oz)

stock solution part 2
monopotassium phosphate (22.7% p, 28.5%k) @ 83.1 g (2.9 oz)
potassium nitrate (13.75% n, 38% k) @ 55 g (1.9 oz)
potassium sulfate (43% k, 17.5% s) @ 177.2 g (6.3 oz)
iron edta (13% fe) @ 8.7 g (up to 14.5 g when feeding high mn)
zinc edta (14% zn) @ 0.5 g
copper edta (14% cu) @ 0.3 g (up to 1.3 g under intense ligh to reduce fruit cracking)
manganese edta (12% mn) @ 3.1 g
sodium molybdate (39.6% mo) @ 0.1 g
borax or sodium borate (11.3% b) @ 3.3 g

stock solution part 3
epsom salt or magnesium sulfate (9.76% mg, 13% s) @ 193.1 g (6.8 oz)

[making working solution]
this should make 100 gal of stock solution.

to make into working solution, add 1 liter of ea stock solution per 25 gal of final diluted nutrient solution.

full strength should be 170 ppm nitrogen. ec 2.0-2.2. 1300-1430 total ppm.

if need 50% solution, use only 0.5 liter of ea per 25 gal...

the formula works weel in soilless mixes such as peat + perlite + vermiculite., the so-called 'peat-lite' mixes widely used in the greenhouse & nursery industries, & in bark mixes & compost + soil mixes. generally, because of the buffering effects of high organic matter in these mixes, the gardener can increase the feed rates slightly (110-120%) as required for optimum growth of the plant being cultured.
if growing in sand, pebbles, rockwool, or other inert, inorganic substrates, use rates of 100% or less.
when used on solid media, apply enough solution @ ea watering to displace the previously applied fert. this helps minimize dangers of salt build-up.
enjoy your garden!

phenotypex, i just re-read my post and it almost sounds like i'm picking on you. i'm sorry, i certainly did not intend that. l don't like bullies and don't want to be regarded as one. thanks for your understanding, d9

The ingredients for these recipes are easy to purchase in the UK I notice:

Calcium Nitrate, 4.99 for 800g:

311.jpg


Sulphate of Potash, 1.25kg for 4.99:

291.jpg


Sulphate of Magnesium, 1.25kg for 4.99:

504.jpg


Potassium Nitrate, 7.50 for 500g:

114.jpg


Potassium Phosphate, 5.99 for 500g:

gggggggg.jpg


Chelated Trace Elements, 6.99 for 800g:

021.jpg


Let's add up the cost of that lot: 35.45ukp

I'd add some humic and fulvic acid to aid chelation, some kelp for overall health and that's about it. Maybe some molasses for carbs. Kelp powder is very cheap from the healthfood store, I get molasses for 6.99 for 5 litres from the animal feed place.

I haven't been able to find a UK source of cheap powdered fulvic acid, anyone know where to buy it?

How many gallons of nutrient solution does that give you? Seems more expensive than just buying a bag of maxibloom which makes around 200 gallons depending on dosage. Seems you need to buy in large quantities to make this worthwhile, which while im sure is cheaper per pound than a premixed salt, its also a lot more money up front. You would never need to buy another nutrient again though. lol.

can somebody check out this fert. i have used to mix my solution it says its not suppose to be mixed with Ca and Mg,so when i asked the guy at the store he told me it should be given individualy but thats when i use it in soil,how im suppose to feed my plants when i cant add Mg and Ca,i did add Mg

heres the link just check :http://www.haifachem.com/lang1/templateltr/default.aspx?maincat=1&catId=12&PageId=37&parentId=45
Multi-MKP Mono-potassium phosphate 0-52-34

this is the only way i can get nutes in my coutry i dont have many options

hi, elito, haifa chemicals is a world respected supplier of high grade ag chemicals. good quality stuff. but why the 0-52-34. it would seem to me the poly feed 9-12-36 or 9-10-38 would be better choices. jacks and totalgro also ship base formulas without calcium nitrate. this is done to keep chemical interactions from occurring in the bag. also many greenhouse growers just add calcium nitrate until they get the nitrate levels they want at different stages of growth. if done within guidelines provided by the manufacturer everything else just falls in line.

i use these for the first 30 days with good results

3-11-38 and 15-30-15 60/40

15-30-15 heres the link for the specs http://www.yara.rs/Products/Ferticar...15+starter.htm so this one has no Ca

3-11-38 Mgo 4%,B,Fe,Mn,Mo,Zn it has no Ca also so i have to add it extra,how much calcijum do i need to add,my tap is 0.5ec so if i want to get the solution to 1.4 can i add thse nutes to 1.2 and then add CA to get it to 1.4 is that too much,is these are % ration of these elements that i need to give to my plants

then i wanted to get something with less N to give the buds a boost and i dont have haifas whole line available in the stores here and i cant get nutes imported to my country so i have to make something with the one i have

1.Mono-potassium phosphate 0-52-34
you can see the specifics on this page http://www.haifachem.com/lang1/templ...37&parentId=45

on the PDF for this product it says it shouldnt be used with Ca and Mg how can i make a fert from it if i cant use these elements,i dont get that

i wanted to use that one for the second faze of flowering after the first 30 days to get 0 N,and i have these
2.-magnesium sulfate:Mgo 16%,
sulfur as /S/ 13%
sulfur as /So3/ 32%

3.-and the 3rd is Micro nutrients
-Mgo 3%
-Co 0.5%
-Cu 1%
-Fe 2%
-Mn 4%
-Mo 0.05%
-Zn 3%


today i mixed these like this

-0.5ec was the starting tap water
-then i raised it to 0.7 with micros
-then to 1.2 with Mono-potassium phosphate 0-52-34
-then to 1.4 with magnesium sulfate:Mgo 16%,
sulfur as /S/ 13%
sulfur as /So3/ 32%

can i use these like that to make a flowering fert.
Mono-potassium phosphate 0-52-34 and

magnesium sulfate

and microelements the ones above

and can i add the calcium nitrate to it

the guyat the store told me i should use the Mono-potassium phosphate 0-52-34 and Mg and Ca separately but how can i do that i dont have the space to have 2 reservoirs for one table and what about DWC how can i use it then,what would happen if i mixed then all together

and can anybody advise me are the mesures i stated above in EC ok or im off,can i mix them like that just mesuring the ec as i add one after the other

hi, elito!

i read your post twice last night, twice this morning with breakfast, and 3 more times this afternoon.

there are so many variables and unknowns involved here i can't even begin to make a recommendation.

i don't have a chemistry background and i think this calls for that. maybe someone here who does can help you. this site has an amazing brain trust. good luck

see post 28 for basic steiner solution instructions...

3 separate stock solutions. mixed together into 1 solution. diluted w/ water. adjust ph. apply.
replace in 7-10 days...

the stock sulotions are only 4 liter, or ~ 1gal. 1 liter of ea of these stock solutions is then poured into 25 gallons of water to make a 100% working solution.

or...

add 1/2 liter of ea solution in 12.5 gal of water.

or...

1/4 liter of ea solution in 4.16 gallons of water...

enjoy your garden!

are u saying that if i mix each of these components individialy and add them one by one to the water to make he solution that i want then its ok to mic Ca and Mg also,that how i did it diluting each component in a 1l of water then mix it in the res. is that ok,can some of these bind or max each other out to couse problems

yes.
the stock solutions should not be mixed together until that mix is in the water which will make the working solution.
they may cause issues if all 3 stock solutions are mixed together & then poured into water.

concept is to keep different chemicals that react unfavorably (for the gardener) away from ea other, until they are in solution.

solution is replaced every 7-10 days, w/ new solution. this decreases chance for chem reaction, precipitation, & eventual lock-out from plants...

the instructions followed should not cause problems. the co you acquired salts from should provide literature & mixing instructions...

enjoy your garden!

Im ordering chemicals as we speak, however im not sure when everything will be in place as i have to order from another planet(shipping-times). Ill give you guys a log and i'd appriciate any input as you watch my plants die in a bubbling sea of anthrax acid... What im trying to say is that i probably need help so stay tuned :p

that what i neede to know,thought that u cant mix these together ta all so i was confused about that,that how i did it mix one after the other in the tank
sorry if im bothering u but your the only one iv heard from that has such knowledge about nutes

about your post #28,is part 1 mixed in 4 l of water and part 2 and part 3 also,so i would have 3 4l containers with these solutions with the amounts u stated,and i have to apply them in the same amounts,but i have nowhere to buy individual micro nutes but like this
http://www.haifachem.com/download/files/Multi-micro_Comb.pdf
can i use this for the micros,but then i couldnt mix it in the ration same amount as everything else,is it possible to make these 3 part solutions then add them to the res. and add extra the micros the ones i have available like if i want to make a 1.2 ec solution is 0.2 ec for micros too little or too much,is this even possible to make like this or do i have to have each idividual element and mix it

what is the NPK for the mix in your post,the reson i got into this io becouse i dont have any flowring nutes so i buy a 11-44-11 and 3-18-38 and mix those but i would like to be able to dose the NPK that i want for the flowering stage first 30 and second 30 days
