Just curious if anyone has a good feeding guide for jacks . I’m running canna coco now , and early veg ppm is wildly high , plus my reservoir smells like a body , after 5 days - with a 5.8 ph and 65* temp … I wanna switch to something much cleaner , or eliminate the stuff that is causing the smell - I’m guessing rhizotonic and cannazhyme?
I’m flushing my reservoir as I type this , and have jacks here minus epsom salts. I have some calmag I can add as well .

any advice is appreciated

Idk what the deal is with the canna coco feed chart , but I pulled rhizotonic , and cannazyme from the lineup - just added a and b at a reduced 80% ratio , and used some gro-tel cal-max , 5ml per gallon and my ppm is still 1230 ppm which seems wildly high on 3 week old autoflowers .
Yes my well water is hard and full of crap “380 ppm”
But subtract that and I’m feeding 850-900 ppm during semi early veg .

I do show light nutrient burn on tips , and definitely had a magnesium deficiency “hence the addition of calmag .
I was running my ph low , around 5.7 but I ditched that and I’m gonna hold at 6.0 . I feel like my pen may be out of wack slightly and I’m walking a fine line to mag lockout ..

I've been running Jacks 5-12-26 for a long time. The simple 3-2-1 formula works great. I'll start a young seedling at maybe 1/4 of this ratio so .75g/gallon jacks, .25g/gallon epsom salts and .5g/gallon calcium nitrate. Work up from there in the same ratio (3-2-1) until you get to the max. Jacks recommends higher amounts than I ever go because I'll get leaf tip burn so I just use 3g/gal Jacks, 2 g/gal cal-nit and 1g/gal epsom salt (magnesium sulfate). Always mix Jacks then epsom salt and cal-nit last.
Here is a link to Jacks cannabis charts for the 3-2-1 mix: https://www.jacksnutrients.com/_files/ugd/3230c0_15ef9a140f114133bb1be94c8e6ad079.pdf

I love jacks . I feed it on my outdoor plants - cheap , effective and produces some very nice results . I’ve got 9+ foot monsters in 10 gallon fabric pots with coco .
Granted they started getting jacks after already being established and growing for 2 months , but they can’t get enough of the stuff.
Autos on the other hand , are finicky.

This canna coco line is driving me nuts . I left out half the ingredients , removed 5 gallons from my reservoir because it was too hot , at 1230 ppm , put 5 gallons of ph’d well water in - and it dropped to a whopping 1150
I run an Apera gs3 EC PEN

I've run jacks in hydro since my first grow, no issues or smell.

I rarely measure to precise, I just scoop and mix. Each run is 3 to 4 auto plants yielding about 1lb of dried bud.

I’ve always been a soil grower . This was my first year doing coco . Definitely a way different ball game , but the 10 ft tall by 10 foot wide 11 week old monsters, in 10 gallon fabric pots in my back yard , tell me it’s got some serious potential . I’ve also never ran jacks before - I used to run emerald harvest in hydroton , in a 24 site ebb and flow - but I had a 55 gallon reservoir , and a very nice sealed room , with absolutely no contamination and very cold 60* at all times .

im feeding 300 gallons of jacks based on their chart , every 2-3 days on my outdoor plants , and watering daily for coco plants with calmag .

my indoor plants are all autos and are definitely not heavy feeders like the big ladies - so im trying to go clean nutes and not burn them , as two of them are definitely sensitive to higher ppm/ec . Thats the downfall of growing 4 diffferent strains in a 4x4

I switched to Jacks 3-2-1 for RO after my second "pretty bottle" grow. With the exception of my last grow, I run the same formula was drop to chop. For my last grow, I decided to try a "Bloom booster - why not? What can possibly go wrong?" Never again. A total plummeting-pH shit show.

I run Jack's now but back when I started Gen Hydro Flora series was all there was. Anyway I use this for 1 week as I roll into flower:
