Just received my bottle of Jack’s 20-20-20 and would like to know what is the best way to use it for mother plants to keep them short and happy. Ppm, ratios, and any general info is appreciated.

Most people feed their mums the same food which they are feedin their plants in veg with ( grow nutes ) this usuaally has a ratio of 2/1/1 or similar , pushing n .
Pushing n promotes stem and leaf growth , so if fed to mums it will push them to grow taller /leafier , mums or any plant if fed grow nutes for a long time 5 weeks plus will start to show p or k def and will need a feed or two of bloom to keep p k levels up . A more balanced feed like 20/20/20 is pushing nothing to the extreme , it’s just happily ticking over at nice pace , so 20/20/20 is a balanced feed for longer time in veg kind of
400/500 ppm maybe depending on pheno and then see colour of plant and adjust accordingly
The lower n in the mums will help when taking cuts as the cuts will have less n stored in them , so they shall root faster ( a cutting that is full of n shall just sit there and take weeks to root , it does not need to fire them out as quickly as possible , as it has enough n in it to survive already kind off )
To speed things up even more , one week before taking cuts feed the mums with a complete feed but pushing p ( you can use your bloom nutes , the extra k will do no harm )
There’s even less n in this feed and the higher p promotes rooting also
Drop the ppm abit too , so as to make them slightly hungrier in that week befor taking cuts

No experience with 20-20-20. Only light experience with mums.
Keep in mind it has no Ca or Mg.
Unless I read the wrong label.
ifish has some impressive info!!!

No, you read it right. I’m going to add about 2.5 ml of calimagic to my water first and hope that does the trick lol! 
I hope I don’t have to get a bag of cal-nit just to feed 3 moms, but I will if I have to.

Are you putting the muthas in coco?
Cali should do it.
Cal-nit has such high N relative to the amount of Ca it gives up.
Jelly. Soil guys seem to be able to run without having to use Ca additives. (I’m a soil dummy.)

I run everything in Coco. Been giving my mom’s the same nutes (maxi grow) as my veg plants just lower ppm. They’re getting a little to big for my liking, so I’m hoping the 1-1-1 ratio of the Jack’s keeps them happy but also keeps them from getting out of control.

Moms will still grow fine and get unruly on MaxiBloom 4-15-14 at pretty much the same rate as MaxiGrow. I’ve used both.

Nice post @ifish
I agree. A balanced fert should be just fine. I’d feed less as well.

I have never used or bought cal-mag and I’m running old ProMix BX medium. I guess I’m one of the lucky ones!
Coco seems like it’s fussy I don’t like fussy

Coco could be fussy, but after you buffer and fill the cations sites with Ca/Mg, it’s an awesome growing medium. I also have no need for cal/mag if using a complete fert with the proper ratios for that particular stage of growth. It’s just that the Jack’s has no calcium or magnesium in it, so I have to add some to my base water to make it a complete fert.
