jacks did come up with a "cannabis " chart. an they did increase the gram per gal ratios.
Jacks part a 5-12-26 at 3.79 Gram Per Gal
part B 15-0-0 at 2.52 gpg
Just talking here..... towards the direction of nutrients an their values to the plant.
I think the most part any of recommendations to run at a final "EC reading" is completely an absolutely based on environment and genetics and stage of growth. What works for Neg37dba might not work for "joe"
throw in lighting differences, wow !! An not just PPFD but DLI as well. Always so many factors.
or PPFD from one lighting diode arrangement to another diode arangement. then PPFD is not a reliable baseline anymore. " but im at 400 PPFD" is now actually kinda vague. this alone can show problems in one garden an not the next.
An like neg37dba said, the choice of medium. the cec of the medium, or WC of medium, all plays a big part on how they feed. among other things.
I miss the RDWC days. But i dont miss moving one pathogen to the next plant. Its bad enough dealing with fungus knats being a vector or possibilty of clone to clone spreading.
Circulatiing unwanted and unknown pathogens is one of the reasons i stopped RDWC. Not root rot either, that was elementary compared to later on. And also reading a reservior EC, but not knowing truely what the individual element depletion is of the nutrient solution. Or worse off, the ACCUMILATION of leftovers throwing antagonisms an chasing phantom defeciencies. Then throw in rasied Na or chloride levels rising. the uncertiany of how valuable the nutrient in solution now becomes less and less reliable. I hit a certain point where the unknowns started to outweigh the benefits.
but If it works for you, full steam forward!!
But RDWC was such an efficient way of hydro growing. i think eventually i will try again one day an incorporate UV lights on my feed part of the circulation.
Then to add, understanding that "EC" is only reading conductivity and that's all.
1ec in a gal of jacks a, is completely different then 1 ec of jacks B. Feed them in a ratio and they work. Seperate them, and feed 1 ec of jacks B(cal nit) over an over an it does not work without the A
I tell you thou, ever since newer leds have came along feedings have gone up an up. but on the plus side yields have often gone up as well. But its like putting ferarri motor in a smart car, if you cant keep it on the track, your not making it to the finish line.
Change any parameter, known or UNKNOWN, an things can sometimes get squirrelly.
Seize the day!!
