Their full strength mix is
Part A: 3.79g
Epsom: 0.99g
Part B: 2.52g
I don't run full strength, I started with autos at 80% strength, which funnily enough is actually the 3/2/1 formula: 3gA, 2gB, 1gEpsom. It works pretty well. I mix 4 gallons at a time so the nutrient amounts guarantee a proper blend of the powder components. A trick I learned from MoG mixing his megacrop. You can up/down the strength by either reducing the amounts in % ratio or just multiply by one less. Example: 3/2/1 x 4 for the 4 gallons and its 12/8/4g each OR just do x3 and use 9/6/3 into 4 gallons. I do bump the Epsom a touch higher for coco. Usually 1.3g/gal insted of just the 1g/gal.
The only thing I add is a liquid silica. I use that as a pH buffer in RO. The Jacks line tends to be pretty acidic. Mixing up just the plain nutrients and the pH ends up around 5.5-ish or lower. It took a bit of test and tune but I can pretty much hit my target pH by adjusting the amount of silica. It holds very very stable for several days, both pH and strength. I bought their full kit, even though I know it was probably far overpriced, especially for epsom salt. Ah the price of convenience!
I do use the clone/seedling product when starting new seeds. I also use the bloom booster during the transition period to flowering. Then it just switches back to the normal 80% strength until the end. I did use the finish on my last photperiod plant and it worked quite well.
There are several far better growers than I using the line. I have only used it in coco so far. Quite easy to simply flush if I see a mistake developing and I am far from good enough to decipher nutrient issues.
You do need to mix in the correct order: A/Epsom/B, or it will get cloudy. Plenty of videos and help/guides on their website as well. I like to mix mine and let it sit for ~20min just to make sure the pH and ppm settle and are where I want them. The powder can take a little stirring to dissolve fully but it does quite easily. Ok that's probably enough of a book eh?
EDIT: The Twenty20 SparkleFace photo grow in my signature was a full Jacks run. Turned out beautifully. Not a crispy/yellowed/malformed leaf on the whole thing.
@McDee check my post on page 184. Use straight up or mod as you like.People are doing all kinds of crazy mods with the formulas. To start you can keep it simple and stick with the 3 main parts and go from there. If they look hungry, add a little more 5/12/26, if you need more calcium or nitrogen, add some more cal nir, if you need some mag, add more epsom. Or reduce if you think it's too much. Each plan/strain will be different and be effected by your environment etc...
For autos I used 60%, full power fulvic, and bumped up the mag a bit and did pretty good. I'm doin photos at the moment and what i'm using is in the post mentioned above and they're doin well enough for the first time using Jack with photos.
I'm no expert by any means, but if you got questions fire away!
Man, that took some time for me to type. Don't type well when this baked!
Removal from Schedule One will be a blessing and a curse! So will federal legalization! The letter released is huge though, even if the justification listed is BS. All the letter said was for simple possession. How many people in federal jail are there for simple possession? Not many. Should feel joyous, but have mixed emotions about the future of full legalization. At least we won't be getting locked up for piddly shit though!!!
I think the biggest thing from Removal from Schedule One is that it will then open up funding for research.
I heard that there were NO people in fed custody falling under this. There are other charges they are serving time for.
Simple possession is a rare thing anymore with the way they stack charges. Just growing will land you a Manufacturing charge along with a Manufacturing with intent to sale charge along with possession.....
4 plants drying in the closet....I also dropped 21 seeds...3 orange sherbet, 2 blue dream matics, 2 pink runtz, 2 gorilla glue, 1 runtz auto, 4 pinky t pink pheno, 4 pinky t purple pheno, and I can't think...of the rest atm...oh ya 4 whisky zulu...that's 22 plants.....going in 9 5gal grass roots living soil pots with sohum cannabis living soil and tealab compost teas....
