hey, ive been buying gallons of nutes and the price plus shipping is kinda high to get them here...ive been reading of people making there own nutes on here to save money,, so im looking for some recipies that have been tried and tested, can anyone help me out so i can make my own.. thanks
 
I'm soil, but as I understand it, familiarize yourself with HydroBuddy first. You could buy something like Jack's Hydro and let HydroBuddy tell you how much to use/mix to get ratios (profile) you seek. Or, you could follow @Hermitian 's schedule for Grow More hydro nutes at the bottom of this page.

Those two products are inexpensive and seems far simpler than buying bags of raw materials. If you want to do the raw thing, you can search this forum for hydro buddy. Also "Yara," a seller of raw ingredients. That might get you some background info.
 
ok thanks i looked up jacks hydro,, so if i understand correctly these can be used stand alone instead of using other products,,, and it only takes a 1/2 teaspoon per gallon that seems like it would go along way
 
Hydrobuddy actually has a lot of good recipes built in to the formula database upon installing. I checked through all the recipes they have to find a range of acceptable ppms for each element, as well as good K:Ca:Mg ratios.

The Hoagland solution is a very good starting point as all hydro nutes are pretty much a variant of hoagland. If you have hard water, my mix #17 would also be a good starting point.

You don't really need zinc or copper salts.. Honestly, you don't really need Mo, Mn, or B either... but they are beneficial to add. You do need iron, so you'll have to get either an iron chelate right away if you want to make a+b stock solutions, or iron sulfate if you can keep the iron in a separate container.

I don't know much about it. If I used JR Peters Jack's hydro products I would use hydrobuddy (google for it) to tell me how much to use to get a desired profile. I think it involves the nitrogen and calcium coming from one bottle, the other stuff coming from a second bottle. You have to mix those to get the ratio you want. You could use my spreadsheet to evaluate such mixing. But, HB is more powerful, more automated. (I did the spreadsheet more for soil, to identify the NPK ratios resulting from multi-bottle "lineups," and recreate it with less complicated products.).

If I used Grow More, I'd follow hermitian's schedule.

I can't help much because I've never done hydro.

I'm using JR Peters. Much, much cheaper
 
yes i downloaded the hydrobuddy im trying to figure out how to use it,, and i thought JR peters was the manufacture of jacks
 
which product is this? can you tell me how your making your nutrients if your using hydroponics
I'm using Jack’s Professional 5-12-26 Hydroponic (3 tbsp) and 15-0-0 Calcium Nitrate (3 tbsp), along with Epson salts (1/2 tbsp) in 40 gallons of RO water to get a solution of 530PPM. Adjust strength to get whatever concentration you need. I mix the ingredients in 1-1/2 gallons of hot water and then add it to the reservoir. Here's a link to their website: http://www.jrpeters.com/Products/Hydroponics/Buy-Hydroponics.html This is my first grow with their products, so I can't tell you what the final results are, but they seem to be progressing as well as they did using other products that cost a lot more. $54 and there seems to be enough for at least six grows, maybe a lot more. You can't get one bottle of the cannabis specific concoctions for that price, and you'll need at least two. I got 8oz of Jack’s Classic 10-30-20 Blossom Booster ($6) to induce flowering for one week, but I'm told that wasn't necessary, that magnesium salts would work just as well. All fertilizers have the same ingredients, you just have to buy a lot of different "enhancers" to get them and pay a ton for them adding water and putting fancy labels on them. Hope this helps you.
 
40 gallons last 2 weeks and almost no pH adjustment is needed. You can get Epson salts at any drug store. $3 worth is enough to last forever and it never goes bad, but will lump up if it gets damp.

yes thats the kinda answer i was looking for thanks,, is there a reason you ppm runs so low,, we usually run our at about 1300 with a total ppm of 1600 from the water?

That was on the 0.5 scale, I should have mentioned that. So that would be about 750ppm on the 0.7 scale. I have found pushing the PPMs too high burns the plants. Where I'm at seems to be enough and doesn't risk nute burn. I started at 300 PPM, with 30 gallons changing every week until recently and have increased it about 100 PPM every rez change..I transplanted them into the hydro system 1-25-2015. My RO water registers 40 PPM, and that is with whatever residue is left in the chiller and maybe 16ozs leftover in the bottom of the reservoir. I have two 38 gallon trash cans I store the water in before use and that registers 0 PPM.
 
My system seem to take care of itself, except for rez changes. The initial mix has a pH of 5.8 or 5.9, I lower it to 5.7 right off and 1 or two days later have to lower it again, then it slowly drops on its own. The current tank is 8 days old and reads 5.4. When it gets to 5.3, I'll bring it up to 5.7 again. I run 1500 PPM co2 and "daytime" temps of 94 F max and 85 "night" time
 
For 300ppm water, Just use slightly less calcium nitrate, and then use nitric acid based pH down to break the carbonate buffer. Carbonates leave the system as CO2, and are replaced with the nitrates from nitric acid.

The mix I posted is for about 300-400ppm tap. on 0.7 scale.

Doesn't that cause wild swings in pH levels? Also, how can you be sure what mineral is causing the "hardness" in your tap water? If it was, say iron, wouldn't that method fail?

Is the water red?
It was a hypothetical question. If the water actually had a red tint, it would have to be somewhere around 50,000 PPM! Or have Fox Farm nutes in it. Doesn't using pH down to remove carbonates cause your pH to swing wildly?
