Jack’s Classic /JR PETERS (Don’t waste money on anything else)

I will add to this but, for now I am going to share my opinion and some links, others will join in.

These are the Jacks/JR that work and do the same and better than the expensive brands.
Soil Based Media (Currently Only Available thru Martins Produce Supplies)
Jacks 15-20-28 Fertilizer AquaGold Grow N’ Bloom (VEG + 2 weeks in flower (3 weeks for long strains)
Jacks 7-15-30 Fertilizer AquaGold Finisher (Remaining Flower)

These are the 3 staples of Jacks that will provide you with the exact nutrients you need to grow healthy plants and have great yields.

You are welcome to use a Bloom Booster and that is why I listed one but, it is not necessary. Actually, I don’t believe in the “BIG P MYTH”

(I add some Canna P/K 13/14 for 1 week and that’s it.) I have only seen a slight boost in yield with higher P/K and that was in a friends grow which was desperately in need of more available nutrients. He was a seriously weak feeder, maybe 0.2EC at most in soil)

Why so little N in their soil nutes? I use 50% nute-less soil (garden mix from local farm) 50% perlite and Dyna Gro Foliage pro, ProteKt, and Bloom currently. I think the closest thing on your list is Professional Calcium Magnesium LX (peat based). I’m hesitant to switch but if I can save money I’d appreciate being informed on what might work for me.

I notice the Jacks nute above doesn’t include a few micros that DG does, namely sulfur, nickel, cobalt, chlorine, and sodium. Will I need to supplement further to get those micros with Jacks?

Calcium carbonate is often times the source of the calcium in your tap water and it’s not readily available to plants. You’ll still need a calcium supplement if your nutrients don’t already supply it.

And a quick comment about the poll options: folks who buy liquid nutrients aren’t paying for water as much as they’re paying for convenience. Complete, one-part foods are plug and play. Dry foods can be messy and tedious to use unless stock solutions in concentrated form are made. That being said, I do buy raw salts and make supplements for a fraction of what retail stores charge.

Jack’s Aqua Gold 15-20-28 NPK ratio is a lot different than FP’s 9-3-6 NPK ratio. Now I know DG is recommended for Hydro, so it seems to me that Jack’s is assuming my soil has some Nitrogen in it? Do plants need less Nitrogen in soil?

My soil has zero added nutrients/fertilizer. Ingredients are Aged bark, peat moss, coconut coir, pumice, perlite, lime, dolomite, gypsum, and natural yucca wetting agent. Jack’s soil forumulas seem like they have way too much P and K and not enough N. The peat-baded formula I noted in my last post has a better ratio it seems 15-5-15, but I could do with less K as I like to add Potassium Silicate 0-0-3 (ProteKt) for the added benefit of silicon.

Re: Micronutrients. Beyond the basic function and use of each micro the article you posted outlines, is the overall point that my soil mixture should already have most of those micros? Do the ingredients in my soil have them you suppose?

Well the “hydroponic” mix can be used in soil also. It is a 2 part with Cal-Nit making up for the Calcium. Trust me there is plenty of calcium in their products.
I know many focus on Cal and Mag as if they were what ensured proper plant growth. BTW, more Cal in Veg and more Mag in Flower. You can do both but the focus is just that.

I am not trying to be rude by any means. If you are looking to be convinced to use Jacks, I am willing to do just that. Otherwise, I set this forum up to be a Jacks Specific and Only thread. Additives are welcome, if the bases are Jacks. I am not a Dyna-Gro fan or a fan of any other company for my base nutrients. Dyna-Gro has nothing I like actually. Their Neem Oil doesn’t dilute well, their KLN is junk and doesn’t do anything, and I don’t use any Silicates (my opinion on that is it’s a waste of money, I have seen absolutely no difference and used different brands over a 2 year period, including Pro-Tekt which I have nearly a full bottle of)

Much of what is put on the market is for us to buy to make them more wealthy. They don’t care one little bit about your end result. They know you are gonna make enough profit with or without the junk they sell you. It’s NPK and Genetics to start with, outside of that is bio-stimulants. Those will only do so much. If you are dialed in, then you may see up to a 10% increase in yield and maybe 1%-2% better THC. Flower smell and stickiness can be brought out with bio-stimulants also. Though, this is for a more appealing product. I would only ever suggest organically made bio-stimulants.
As for beneficials, I do believe they help in the health of a plant and humic acid in great stuff for better Brix. You, have to realize everyone wants Cannabis Cup winning weed, but spending your entire paycheck to get there isn’t worth it. The best tomato or corn or apple isn’t inundated with as much BS as cannabis is. Yeah, an apple isn’t getting you stoned, but next time you smoke some bud, tthink about how much effort was put into that bud and the bud you spent half that cost on. I bet it wasn’t any better. You, will have to be subjective to the fact that you probably didn’t grow the same exact plant over the two trials. I can say I have, and many times. Most strains last about 1-2 years in my Veg room, and I keep 5 mothers at any one time. Currently, I have mothers of Super Silver Haze, Hashberry, Underdog Headband, Northern Lights/88 G-13, Thin Mint, Galactic Glue. My Super Silver Haze mom went into the bloom room 2 days ago, I had her for over a year now, but shes a keeper so I have a new mother growing of her.

    Jacks Professional Schedule?

    Anyone else using Jacks? During bloom and transition phase do you also include the Calcium Nitrate?

    I got an answer to this so for the sake of sharking knowledge I will answer it.

    Run both until about 10 days before harvest.Then drop the Calcium Nitrate.

    My source is a chemist and engineer. His name is Fatman.

    Horticulture grade fertilizer. Its the highest standard for your plants. Bascically instead of spending $500 on “nutrients” from companies you can spend pennies and not need to buy any additives. Jacks professional 5-12-26 combined with Jacks calcium nitrate 15.5-0-0 gives you everything Cannabis needs. (give or take depending on your water source) Im talking mixing batches for pennies. Faster than pouring the liquid nutrients too. Jacks also does fertilizer testing for your nutrient solution. I think of nutrient companies as those instant rice and instant food. Its way overpriced for the quality your getting.

    You can buy 25lb bags for about $35. So an example is you use 2 tablespoons per gallon.

    I jumped off the “nutrient” bandwagon recently after reading some comments online about not using bud boosters because 95% of them are just sulfur and magnesium. After digging around and visiting a LARGE scale commercial hydroponics farm. When I asked what nutrients they used I got laughed at. Jacks professional will give you a very close ratio to what cannabis requires and has everything in really nice amounts. Pot growers get ripped off by nutrient companies.

    My Jacks arrived today. 5-12-26 15.5-0-0 Anyone else using Jacks? During bloom and transition phase do you also include the Calcium Nitrate?
