Jack's Classic growers

So I got an email back from Jack's and I stand corrected. I was wrong, so before I dive in to the info they provided info, I owe churchhaze and jbone an apology. I was wrong, and an asshole. So again, I am sorry.

Neither Jack's that I use has calcium in it, And even though it is water soluble, running it would wasted nitrates which could cause a problem. So those are the facts from the horses mouth.

Eta they mentioned to get around these issues to run their two part hydro line.
In regards to differentiating hydro vs soil foods, you can always tell by the ingredients. Hydro foods always have lots of nitrate N and the rest of the important elements. That's what stuck me as odd when reading AN's Connoisseur label which claimed their nitrogen was made up of only 26% nitrate, 18% Urea, and 56% Other water soluble Nitrogen. See, that label strikes me as a plant food intended for container gardening....or at least I hope it is because it was awful, and I mean AWFUL in hydro.

Yes I made the mistake of thinking of it was from a different source. Reading comprehension fail on my part. Thanks homebrewer for clarification.

Eta I was thinking there was calcium nitrate

can someone running the jacks 2 part hydro give me some info on the ratio and amounts that i should use? curious if/when the ratio should be changed going from full veg to transition flower and then to full flower. also, id rather not premix a concentrate but instead mix the nute in the 100 gallon rez. is this ok? does one need to be added and fully dissolved before adding the 2nd?

cheers

Hey guys...Last grow was going good until I had to cut it short but I was using the Jack's Classic....

My medium is Pro-mix HP, worm castings, perlite, and dolomite lime....

Would I be ok to go with the Dynamic Duo this time around with this medium ?

Thanks, SC

The ratio is 3 parts base to 2 parts cal nitrat by weight. it is designed with different size particles to
be close to that when used by volume 50 50 with the supplied scoop.
the formula works great in both veg and bloom i like a max of 1.1 ec with this line
as at 1.2 ec and up i find the potassium a bit high.

and how do you mix the nutrients? can i just dump one in, stir til dissolved then add the other?

doesnt matter which goes in first? or if i use epsom salts? i have heard mixing some ferts in the wrong order can cause reactions between them resulting in precipates that are unusable by the plants.

cheers!

In general, you're supposed to mix the calcium nitrate in last. It shouldn't matter too much, however.

Jacks hydro has a LOT of magnesium in it. It comes with instructions for adding an additional small amount if desired
I have never found it necessary

Can anyone tell me if jack's is considered organic ? Do you have to flush at the end ? I'm worried about chemicals, ans I am wondering if I should start going organic. Thanks sc

there is NO nutrient that comes in a bottle that is actually"organic"
organics is breeding microbes and fungi in soil. those beneficial bacteria in turn feed the plant. you in turn feed those bennies with organic materials. Not bottled nutes. If you want to use bottle nutes,look into peat moss or coco. And flushing is bullshit. feed you plant what she needs and don't over feed and you won't need to leech any excess salts, but most of all. Start reading, you have a lot of misinformation that you need straightened up.

Everything is a chemical, even water, in fact, water is responsible for more deaths than lead, arsenic, and mercury combined! Once, some guy killed himself by drinking too much water to win a Wii.

The reality is that the bacteria in the soil create the same nitrates that come in the bottles.

Plants will always eat the same chemicals (nitrates) regardless of how they're provided (bacteria or human).

There is no magical "chemical". Everything your plant eats is on the periodic table.

I had problems with this causing considerable precipitant in my rez. I decided to follow the directions and it worked a lot better for me. I found the easiest thing to do was mix 10 teaspoons of calcium nitrate with plain tap water in a 16 oz bottle and mix 10 teaspoons of the hydroponic nutes with plain tap water in a separate 16 oz bottle. Then I just measure what I need at 50ml of premix = 1 tsp. of dry nutrient. Mixes easier this way and for me the pH has been much more stable.

My tap water could be part of the reason why I need to do this. I have read many others say they can mix straight in the tank, but it doesn't work for me. Honestly, I find either way to take about the same amount of time.

thanks, this is the 1st hand experience i love to hear. i will be doing plenty of experiments on a smaller scale before mixing the 100 gallons.

I'm a newb grower and after reading this thread I'm seriously considering buying some Jack's Classic and maybe some Jack's Citrus for flowering. I have a few questions. The instructions say to mix 1 tablespoon per gallon of water. Will this be ok and if so how much of said gallon should be poured around each plant? Also, how often should I fertilize during the veg and flowering stages? I know these are simple questions but I'm new to growing of any kind.

I love Jacks classics, cant recommend it enough. I ran a test between Jacks and Dynagro, both plants were identical clones, and Jacks slightly beatout Dynagro. However, Dynagro is really good fertilizer and for those who cannot obtain Jacks, Dynagro is where its at!!
You can buy Jack's directly from the maker online cheaper than you can buy it locally.

If you are shooting for 100 gallons I would definitely premix. I'm thinking 2 liter soda bottles would be about the right size. It's easier to work with if you don't get the dilution too strong. You'll have to work out the math, but it's a lot easier to shake a small bottle than to stir a 100 gallons. The 16 oz bottles work great for 10-20 gallons.

has anyone used honey (pure clover possibly) mixed with jack's AP/BB?

thinking about substituting it for molasses.
