Seems like it. It's really a disservice to their customers. You get newer growers with the "more has to be better" mentality that end up with crispy fried plants asking what nutrient deficiency they have when they have nutrient toxicity.
I agree. I guess Jack's has jumped on that bandwagon now.
Its plant and feed dependent. Here is a photo of my grow. At week 4 of flower I went to 2.4 and I kept it there until week 6 or 7, and while the buds got pretty respectable in size, you can tell they are burnt to shit. I think if I had, say, a scorpion Diablo and CO2 suplementation, 2.4 EC might have worked, but as is I think I jumped the shark by at least .6 EC. Its also a bit strain dependent, so unless you are trying to experiment with a strain over multiple runs to perfect it, its going to be a bit of a guessing game.
Don't do 2-2-2, that doesn't sound necessary. The 1 at the end is just magnesium, some people get away with just using Jack's A/B, but 321 does well with LEDs-I need the extra mag anyway. Using that 321 ratio you need to find the right EC for your plants. I rarely flower higher than 1.2 and I've been much happier with the quality of the flower at lower ECs, but each person's setup is different and some people do like higher ECs.
They have jumped on the cannabis bandwagon. I don't blame them as they're a business and the goal is to make money.

I emailed them about this after buying 25 lbs bags of A+B, asking if they have any thoughts on using lower EC with different styles of hydro.They have jumped on the cannabis bandwagon. I don't blame them as their a business and the goal is to make money.
But they now have feed schedules with 6 different products not counting epsom salts. It used to be just the 5-12-26, calnit, and epsom.
Example of their cannabis lineup. Chances are you won't notice any difference than just using the 3-2-1 but this gives them 4 more products to sell.

I listened to a podcast with Jack's reps talking about the bloom formula, and I think it might be worth using. I like how they say to cut out the 321 for a couple of weeks while you use it, so it's not adding a bunch of PK on top of the base nutrients.They have jumped on the cannabis bandwagon.

Wow, looks fantastic (despite the burns).
I'm not saying it's a bad thing. I have nothing against the company. Hopefully more people will use their products for cannabis and move away from the overpriced cartoon labeled nonsense. At least with Jacks they are not playing stupid games and making ridiculous claims. Plus they are very open about the ingredients in their products so you know exactly what you're using.
I just fed with bloom formulae. yes, it's strange, no calcium. I wonder if that was a practical decision, since the goal was to make a 1 part bloom booster formulae, and they didn't want to risk precipitation...I'll check out that podcast. Thanks!
...of course, I can be wrong. I feel like something has changed. I recall Gene Green's YT video breaking down the elements, and the ppm coming out to be around 800 with the 321 ratio...maybe he was wrong? lol I don't know...
I'm almost certain this is the case. Calcium is one of the most important nutrients for a flowering cannabis plant. This product seems more about selling bags than selling a product that works better in this situation than A/B. This new cannabis lineup is just Jack's powdered take on selling a 12 different liquid nute bottles.
That's a bit of hyperbole.
All good, hope this can be of help.Wow, looks fantastic (despite the burns).
I see that your medium setup is similar to what I did a few years ago but failed due to spider mites. I used a fabric batting instead of coco mats. I'm about to try again with a couple of plants, and want to ask you:
Did you stay at the 321 ratio throughout flower?
Are they in 4 inch or 6 inch cubes?
In your flood and drain, how high do you flood to? Eg., top of the cube/half way up, etc..
How long do they stay flooded before draining?
DTW or recirculating?
Anything I should watch out for? Any tips or tricks?
Srry for all the Q's. I'm excited that someone succeeded in a system I'm about to try again after failing before.
Thank you very much! Yes, very important insights and experience. Much appreciated.
