I bought part A and part B off of Amazon about 2 months ago. I’ve also bought straight from Jacks website.
Like @fano_man said, might be mis print.
Use the schedule with Epson salt @ 1.00 grams.
@Myfriendis410 im not sure what you mean. Im thinking those are definitely schedules but they can be tweaked if necessary. I actually can’t find the word adjustment lol, but I could be wrong
This is my 2nd grow, 1st with jack’s so if I sound stupid I apologize
I planned on using those measurements/weights as indicated throughout the growing process. I have no base other than my soil. I was going to wait until happy frog was under 1000ppm at runoff or in slurry before I begin with jack’s
I was looking at the check marks in the columns under each grow cycle. So for flowering I add A and B and epson each time I water through flower stage except at the very end I would use jack’s finish and epsom. For Bud set, I would just use jacks 10 30 20 bloom and epson salt
Jack’s 3-2-1 ratio all the way through grows gucci plants. You don’t need all of the other supplements. If you want, you can modify the schedule the first 3 weeks of flower and do a 2-2-2-1.2: Part A, Part B, Epsom and MKP (monopotassium phosphate) as a bloom boost then return to 3-2-1 formula.
You’re making it too hard on yourself by over-thinking it. I also add silica about the time I flip when I SCROG and discontinue about week 5 or 6.
Print that schedule and read the whole thing, then follow it.
And silica if you want it. Be sure to mix silica first.
Just to be crystal clear: 3.6 grams of Part A is 3 times the Epsom. Part B is 2 times the Epsom. You could mix 3 grams of Part A, 2 grams of Part B and 1 gram of Epsom. The numbers I quoted though give you a decent solution concentration.
