Jacks Classic?

I'm currently on my 17th day of veg on my first grow.

I've been doing some research on nutrients and I decided on going with Jacks Dynamic Duo.

My question is what's the kind I should use? Is the dynamic duo something I could benefit from?

heres a link of the different kinds:

If there's a better option they have or that's most common please don't hesitate to inform me!

Thanks in advance!

I love Jack's classic but make sure you have either cal mag ready or proper amounts in your medium.

ETA it really does work great start to finish. I usually switch to Citrus after week 2 or 3 during flowering.

if. You have any direct questions, I'd be happy to try and answer them for you.

By the way, if you have any questions, Jr Peters has excellent customer services. They answered a couple questions of mine (and corrected a misconception I held). By the way, I didn't mention cannabis when I asked my question just in case you do email them.

I'm finally getting to the end of my tub of citrus, and thinking actually of switching to their hydro line, even though I'm running Happy Frog. I may actually email them to see if this would be a good fit. For about $80 shipped, I can get 4 lb bags of their 5-12-26 and 15-0-0 calcium plus the micros.

Perhaps Uncle Ben could weigh in or someone else knowledgeable in this manner.

What you are using now is what you should be using, if you want to switch to the hydro line and still grow in buckets then do some hempy buckets. If you do switch to a hempy and want to use the hydro line you can buy your own Calcium nitrate for fraction of the cost they sell it for from a garden supply center or online, all they did was put calnit in a pretty package and mark it up a bunch, like shysters, I think thats the common term used around the forum. Jacks is great for soil but im not sold on the hydro line.

I have used Jack's Dynamic Duo for many crops.
Works quite well.
I switched to Jack's Citrus FeED only for my most recent grows.
I am more than happy with the results.

BTW, my medium is ProMixBX amended with perlite and vermiculite and a generous amount of dolomite lime.
Good Luck.

Thanks, but the question is could I go that route? if I did, would I encounter any issues?

And not sure if you saw my old post, but I wanted to apologize to you and admit you were correct.

edit 4 lbs each for $60 isn't bad. Hence why I am asking.

I really like the idea of Jack's hydroponics. I agree with Jbone that they basically take agriculture grade calcium nitrate (a double salt of ammonium nitrate and calcium nitrate commonly just called calcium nitrate), and slap their label on it, but I don't see how this is a huge problem.

http://en.wikipedia.org/wiki/Calcium_nitrate#Use_in_fertilizer

If you don't want to pay for the Jack's calcium nitrate, get yara calcium nitrate. It's literally the same double salt. Yara calcium nitrate is what i currently use and it's a great value. You can get small amounts here, and lots of other places online.

5 pounds of yara calcium nitrate for 7 bucks. Awesome. Their hydro-gro 4.5-14-34 product looks interesting too. It's meant to be used just like Jack's hydroponics so it's a comparable product but cheaper. (I haven't tried either Jack's hydro or hydro-gro, but in theory they're very similar2 part products where 1 part is the calcium nitrate double salt)

(Edit: I also agree with Jbone that Jack's classic is correct for happy frog. Jack's hydro would be good for a sand/perlite/coco/peat type medium, but not clay/silt based medium)

Well of course you can use the hydro line with happy frog but im not getting why you would want to. Why spend the time trying to get it dialed in when what you have works great. If you want to try the hydro line then run a hempy or a dtw run, both will shave a couple weeks of veg time and then you could pretty much run the hydro line as directed like you do now. Like I said im just not sold on the hydro line. I was going to do a Jacks hydro hempy, a foliage pro hempy and an OC+ hempy this run but I pushed it off til next run, iv read some pretty good stuff about OC+ hempys so am itchin to run one. My thoughts are hydro nutes are for hydro, not soil

Cal mag is a bit pricey and I (probably karma due to my dickisness, raised its head late in flower on me, caught it earlier) perhaps you are right. Any suggestions if I stay the classic route, which I am overall very happy with, to make up the lack of calcium? So I could just pick up calcium nitrate, correct?

Any online sources you'd recommend for purchase? Or something available at a home depot?

ETA: I don't think I'd run into problems dialing it in, as it's simply alternate between the two in use, and Jack's is quality. but I'm all about keeping things cheaper and simpler.

thanks.

Imo, calcium nitrate (the form of calcium in cal-mag and in products like GH flora micro) is for hydro while limestone is for soil (clay/silt). I don't think it's a good idea to mix and match even if it does work to use hydro products in soil.

Calcium nitrate is the key to hydroponics.

If you ever did want to buy cal-mag for hydro, however, you'd save a lot of money just buying calcium nitrate and using that. I think cal-mag is the biggest ripoff product on the market, even more so than any AN product. Calcium nitrate is actually the cheapest ingredient in my hydro formulations. I just can't understand how it's become standard to buy bottles of watered down calcium nitrate (cal-mag+) to a point where cal-mag became a word (like Vaseline).

Cal-mag+ is snake oil. It's like the old tonics and elixirs of the past before we had codified standards.

I don't disagree. I bought it back in the day with fox farms but I'm experiencing a calcium deficiency and used it to correct the issue as of now. I don't mind amending nor simply buying calcium nitrate.

Eta bottles almost out so thinking ahead

Thanks for all the useful information guys. I'm still learning a lot of stuff, so a couple things you're conversing about are jibberish to me lol. I'm definitely looking forward to the learning experience and can't wait to see the actual results.

I'm still debating, but the Dynamic Duo seems to be right for what I have going on.

The reason I dont like using hydro nutes in soil is the hydro nutes have everything in them, so you end up with a lockout thats a pain in the dick to fix, they cost more, and they just arent needed.

Lock outs are a pain, but I haven't really had one since I bailed on Fox farms, unless I count lack of calcium as a lockout. It's weird, seems like I deplete calcium around week 7-8 in flower. So a bit of prevention to starve off these problems. Got two clones running about 2 weeks behind one another. started getting the signs on the older one, treated both. Second plant two weeks behind has no issues. Missed it on a couple of plants I recently harvested and want to prevent it in the future.

edit to add when I had problems, I ph the soil and nothing was outta whack.

When I run a soil grow I use Dr. Earth potting mix. I add about 30% perlite. I transplant one time from a solo cup to a 5 gal bucket, when I transplant I top dress with Dr. Earth organic veg mix, when I flip I top dress with Dr. Earth organic bloom mix, week 3-4 of bloom iI start feeding Jacks bloom. Iv never had an issue doing it that way. I have run the organic top dressing til chop without the Jacks but since I had the duo for my veggies anyways I used it and had a better harvest. I dont like anything Fox farm, I know people love it but I think they are worse that AN.

i get it for so cheap and i don't feel like changing up. Happy Frog is always consistent and i haven't gotten gnats like i did from Ocean Forrest. Not to say it can't happen, but the shit works. Don't feel like changing yet as I got it where I like it drainage wise and predictability. Plus a couple bags left as they had buy two get one free. So three bags for about $18, which will be a while anyways.

edit let me Google this dr. earth you speak of

Thanks for the suggestion on Dr Earth. They have the soft rock phosphate which should fit the bill. Grabbed it off amazon for $15.18. I like the fact they seen to have a lot of single ingredients.

I'm thinking of switching over to Jack's from FF Trio, growing in soil. So bottom line, should I buy the Blossom Booster or Citrus Feed for flowering stage?

is there a difference in your grow by using the Citrus? i'm currently using the dynamic duo and am wondering if
adding that in the mix would do some good or i could just wait until my next grow to use that.
