They are boosters and can be used with jacks.
Another vote for Jacks

And another vote for Jacks. I started with FF trio and quickly moved to Jacks - did the 6lb kits but decided the 25lb bags just made more sense in the long term.
Happy 420 all!

I started out 100% organic when I first began indoors in a tent. Now, after @SilvaBack203ās info and guidance, I am a 100% Jackās user. My first several grows come nowhere near close to what I am achieving now. I bought the larger bags right before everything got crazy with prices and shipping. I think Iām good for 10+ yearsā¦

Stay with fox farm if thatās what youāre comfortable with and run it half strength. You probably wonāt notice any difference honestly

Iām 8 grows in, now w/6 Jack Hererās 52 days old, 14 days into 12/12 mode. Iāve used FF trio every grow so far, mixed up 30 gallons a time. I also add 40 drops of T drops for fungus gnat control. I use about 1/2 the recommended strength or 1500 - 1800 ppm. For 30 gal. 3 cups Big Bloom, 2 cups Tiger Bloom, 2 cups Grow Big. I buy it by the gallon about 5 to 6 grows per gallon (of nutrients).
So far every grow has been wildly successful. Some of the most potent Iāve smoked. I do supplement with Cal Mag once per week starting 2 weeks into flower.
Iāve used FF Coco Loco for soil in 3 gallon bags. And use the powder bud enhancers by FF at the appropriate time. And flush with sledgehammer ever 5 weeks or so. Been harvesting about 100 -110 days out.
Right now Iām going to stick with what works! Just my (long) 2 cents:-)

Do you use both of these at the same time? I guess i can check their feeding schedule and this seems alot better than liquid nutrients. So you just weigh it with a scale a dump in ?

Ok i did my research and i think i may try this out. My only problem is i cant find the jacks epson salt on amazon. Do you guys use it ? Jacks 321 website says you need part a / part b / and the epsom salt. Do i need the epsom salt? Thank you everybody
Jacks products for the win.
And yes you will need Epson salt.
Get the epsom from any grocers just make it has no scents or additives at all.

Exactly.
The ingredient list will say Magnesium Sulfate USP and nothing else.
This is equate from Walmart
You only need like 1/4 teaspoon per gallon, so it lasts a long long time

Ok after doing my research i understand how jacks 321 works and this route will be alot cheaper than foxfarm. Does jacks 321 have cal-mag in it?

It has calcium. The Epsom is necessary for mag.

Search Jackās Fertilizer on youtube. There are videos that tell you exactly how to use it. Contact the company and discuss cannabis production with them, theyāll guide you & answer ALL your questions. They even offer a service where they will test your water, give you a report and give specific advice. And you can reach out any time you need - GREAT customer service!!!
Since, weāre on it, thereās some growers having lots of luck just using Jackās Part A (5-12-26) at 4g/gallon, and Part B (CalNit) at 2g/gallon, leaving out Epsom totally.
I actually use Jacks in coco and have been using 4/2 with nice results. Super frosty buds coming in. I bumped up to 5/2.1 this batch and have zero issues so far. After adding 21mlās of silica to 5 gallons of 0ppm water, I add the Part A, then B, and my pH hits 5.82, with ppmās at almost 900 exatcly. Last batch hit 5.8pH and 930ish-ppm because Iām in flower.
