    I’ll be flowering soon and got some Jack’s Classic bloom fertilizer. Never tried it but I heard good things about it. Looking good btw!

    Holy crap — barely two minutes in and totally (I mean TOTALLY) wrong on the nutrient ratios for 3-2-1 Jacks Nutrients. Saved some time — no need to watch any more.

    What about a 2010



  6. Mike Ross on August 31, 2022 at 1:26 pm

    Haha he said "so much THC that it’s starting to curl up those leaves"….



  7. Art Ochoa on August 31, 2022 at 1:27 pm

    Mids at best



  8. Tom R on August 31, 2022 at 1:27 pm

    You confused part a and b dude. A 3.7, b 2.4 Epsom salt 1.1 grams.



  9. John Constantine on August 31, 2022 at 1:28 pm

    Too much nutrients, that’s why bud at almost all dispensaries, have a chemical nutrients smell and taste.

    This vid is so screwed up…"THC curling the leaves" to the measurements. Don’t smoke anymore bro.



  12. Tom R on August 31, 2022 at 1:31 pm

    THC rails don’t curl leaves. But misdiagnosed nutrient deficiencies do.



  13. angel figueroa on August 31, 2022 at 1:32 pm

    I was given a whole different ratio .

    Alguno me ayuda como usar el 10-30-20 para mis plantas? No me queda claro cada cuanto se puede usar



  16. Charles parson on August 31, 2022 at 1:33 pm

    Has anyone ran the master blend. Don’t see a lot of info on here about it



  17. Pooky35 on August 31, 2022 at 1:35 pm

    Austin, love your videos man!, The proper mixing rates are: 3.7 grams per gallon of part A, 2.5 Grams per gallon of Part B and 1 Gram per gallon of Epsom salts. This should give you an EC around 2.4 or 1200 ppm (using a 500 scale).

    Keep up the good work and Jacks is the best!



  18. M O on August 31, 2022 at 1:35 pm

    I don’t think packing on thc=leaf curl



  19. Joe & Michelle Gutierrez on August 31, 2022 at 1:37 pm

    Just started using jack’s 321. Can’t wait to see my results. Thanks for sharing.



  20. HasaniRedd1 on August 31, 2022 at 1:40 pm

    You mixed up the order of the nutrient dosage sir



  21. Boon Vang on August 31, 2022 at 1:42 pm

    Thc makes leaves curl? Damn I thought this whole time it was heat. Shit gotta put my light closer then.



  22. Steven Julian on August 31, 2022 at 1:43 pm

    Great grow op !!!! Great info man cheers !!!!



  23. Asshat 38 on August 31, 2022 at 1:43 pm

    Strains look nice. Stacking up good. Week 6 , Molasses time



  24. Kev G on August 31, 2022 at 1:44 pm

    What do you think about Jack’s 20-20-20 ?



  25. joonas lehtonen on August 31, 2022 at 1:46 pm

    I use ghe/ta flora series as basic nutes, i also have their g.o. bud bloom booster. Now i bought their ex diamond nectar now called fulvic acid. What order do i mix them in water? Their website dont have mentions of any order. I know how to mix flora series to water but what if i want to use flora, g.o. bud and fulvic acid all together? What would the mixing order be? Please help me quick!



  26. christophe 54 on August 31, 2022 at 1:46 pm

    Cool man que dieu te bénisse mon frère merci



  27. 25Patman on August 31, 2022 at 1:47 pm

    do you autowater with this?



  28. Ryan Watson on August 31, 2022 at 1:47 pm

    ratios are oppsite of what they are supposed to be.



  29. John Howard on August 31, 2022 at 1:50 pm

    Love the plants,look great,tacoing is stress related watch your temps in late flower,keep up the great work buddy



  30. Mike Jones on August 31, 2022 at 1:54 pm

    Jack’s is vary affordable and will out grow a lot of over priced nutrients.



  31. Frank Diaz on August 31, 2022 at 1:54 pm

    If you are reading this the nute game ends here. Its cheap… it works… low PPM’s with tap water (740ish) Huge frosty results.



  32. Raymond Robbins on August 31, 2022 at 1:55 pm

    3.6 of jacks feEd part A 2.4 Calcium nitrate 1.2 epsom salt



  33. Dohn Jough on August 31, 2022 at 1:55 pm

    Hey Austin.. How do I use Jack’s Blossom booster, should I stop Jacks 321 and only use the blossom booster alone when I go in to flower? Or combine both together in flower? thanks



  34. twzagame on August 31, 2022 at 1:56 pm

    Wow they look amazing. Nice job



  35. Tree on August 31, 2022 at 1:56 pm

    Per Gallon
    Part A = 3.6 grams
    Part B = 2.4 grams
    Epsom Salt = 1.2 grams
    JR Peters says as long as your runoff is below 3.0-3.5 EC (1500 ppm max) there is no nutrient burn. I have found this to be correct!
    Try their new 7-15-30 line of nutrients specifically for cannabis in the last two weeks of flower! (Start @ Week 7) It is amazing!



  36. michael Taft on August 31, 2022 at 1:57 pm

    3g of the nutrient, 2g of the cal-nite, 1g epson salt..its so simple i dont get how he thinks he can teach but doesnt even know the basics, if he used the formula he described his plants probably would not make it long ,dont think this guy even mixes the nutrients, obviously not the brains of the operation



  37. Jamie Sr. Ferrante on August 31, 2022 at 1:58 pm

    Thanks brother.



  38. Maus on August 31, 2022 at 1:59 pm

    Hey Austin, I’m using Jack’s 10-30-20, 3-2-1, and then finishing with 7-15-30 as I believe you are. What is your source water? Are you on well, municipal, or RO? When I use 10-30-20 in particular I get a really bad calcium deficiency. I am wondering if you’re on well or municipal water thus satisfying things until you start getting Ca from 3-2-1.



  39. AR on August 31, 2022 at 1:59 pm

    That was completely confusing. Lol so since you got the mixing order wrong…its the blue bag 3.6g per gal.. are you telling me you do 3.6 of cal nit in flower? Lnao…no clue what this guy is.sayin



  40. Eddie B on August 31, 2022 at 2:02 pm

    Looking Chunky!



  41. Country At Heart Finley on August 31, 2022 at 2:06 pm

    WOW brother. thanks for the tips. I’ve used Jacks for the past yr but I am definitely missing a bag or 2. its some new stuff im not used to and the directions are not that clear to fallow. thanks for the tips ill be fallowing your channel for sure. nice buds by the way.



  42. Fisher on August 31, 2022 at 2:08 pm

    Have you tested for heavy metals using Jacks yet? That’s the only thing that concerns me



  43. Rezvibe on August 31, 2022 at 2:08 pm

    Why we’re some of the lights off?



  44. Steve Thetford on August 31, 2022 at 2:10 pm

    5-12-26 3.6g ,mix first second mix in 1.2g epsom then 2.4g calcium in that order



  45. B Lee on August 31, 2022 at 2:10 pm

  48. City of Trees on August 31, 2022 at 2:16 pm

    Do you need flower boosters with jacks?



  49. Sheska on August 31, 2022 at 2:17 pm

    Thank you very much for the update! Sadly I’ve looked before but can’t find a Jacks reseller in Europe.
