Making my own salt fertiliser for coco

[Coco_nuts]

Hi guys

Id like to mix my own salt fertilser, what do you think:



It matches up allright with h3ads rezipe:

N 97
P 60
K 105
Mg 27-67
S 41-61
Ca 97

How do i add iron,manganese,molybdenum and cobalt? These micros arent in the salt mix calculator for some reason.

EDIT: i see i screwed up the calcium, need to bring it up to say 100ppm. Although i often have calcium issues and have to amend my coco with dolomite lime, maby i should raise it somewhat?

Save yourself the time and go with Jack's Professional Hydro and Cal-Nitrate. I doubt you'd save much making them yourself versus Jack's unless you're getting salts by the ton... which would be rediculous...

The other reason to do it is so you can muck around with customized formulas that use different ratios than something like Jack's.

Well im using GH 6/9 right now. Cant get Jacks i live in africa.

If i mix my own fert i can have custom profiles for different strains. I have a strain now that is showing a cal deficiency while the others are all fine.

Also i can get all these chemicals for cheap, much cheaper than paying $50 a month for GH. The scientist in me wants to fully understand plant needs and mixing my own fertiliser is very interesting to me.

can u get canna ? will make life so much easier ,just get canna coco and their feed ..works better than any other attempts, including gh 's with greatfull heads ratios ,,which have come into question lately by krunchbubble who has increased to 10/15 ,,canna works ,,no fucking about

 

[Coco_nuts]

No i cant get canna.

Well im sure you can increase to 10/15, but you need the wattage. For instance if i give my cfl plants 6/9 then burn, so they get 3/4.5. Outdoors i gave them up to 8/12 with no ill effects. AFAIK its not about the strength its about the ratio. I read his whole thread and he said you can increase the ppm as required, just keep the ratio, so i dont know how it has been "called into question".

Look im interested in mixing my own fertiliser i dont need 100 guys telling me about alternative products to use. I live in Africa im FUCKING lucky i have a grow shop that import GH flora series, he doesnt even have Flora Nova or half their product line.

hey Coco nuts...salts will cost ya less than .03 cents per litre of res or less than 3.00$ .ca for a litre of A and B at 200x concentrate...the formula you posted shows all of the N supplied by amonimum nitrate=17.5%NH4 and 17.5% NO3 =bad

What should i use?

you should check out funkymonkey diy nutrients thread ,,,if ya read thatyou will not need to ask that ...this is kinda the wrong place for this thread anyway

Coco,
I don't think that K2O is potash. It's potassium oxide which when dissolved in water produces KOH, a strong base. K2O isn't used as a fertilizer.

"In fertilizer terminology, potash refers to potassium oxide, or K2O.
For example, a fertilizer with 0-0-60 analysis will contain 60 percent K2O equivalent by weight. This is somewhat confusing since the fertilizer material doesn’t actually contain K2O, and plants do not take up K2O. It’s simply the standard that has been adopted and used for sometime now."

If I went and bought 0-0-50 fertilizer, it would be called potash and would contain potassium sulfate.

I also wasn't aware that CaO, quicklime, was used in salt fertilizers. When you add it to water, you get slaked lime and calcium carbonate. The carbonate is insoluble and the CaOH drives pH up. The carbonate is a component of agricultural lime but I believe it is added into the media, not into a solution since it doesn't dissolve.

You can use Cal-nitrate to get your Calcium and substitute some of the ammonia with nitrate. You can use Potash to get your potassium and some sulfur.

Good advice from poipu on the diy nutrient thread. Also the low N myth and the high P myth thread are both full of technical information. Although I don't see why this forum isn't a good place to discuss a nutrient solution for coco growing.

BTW,
If you want to start formulating with salts to match something you already have, simply look at the bottle. It will give you the salts and you just need to play with the ratios to get what you want.

Thanks bro, need to get round to looking at this, been so busy, i have like 5 litres of GHE to work through though so have time.

Hey i tried to find this diy thread by funky but having difficulty with the search function... can you possibly direct me? Thank you.
