well so far with the control tests i have done, got 3 diff rooms...
room 1: flushed thoroughly with florakleen
room 2: continued normal feeding but added water between fert(water fert water fert)
room 3: fed at 1.5 EC once every 10-14 days(2 times in a month)
all plants were grown from the same clones, started the same time, andhave been grown under the exact same conditions, same soil
results
Room 1: the flush certainly removes ferts from the soil so they do look slightly deficient but the new growth is nice and green and vibrant healthy, new growth is GREEN with NO PURLPLE VIENS
Room 2: no changes, intervienal chlorisis has continued, purple racing stripes running up and down the stems all the way to the top, looks like classic lock out. usually this is from the salts sucking the moisture from the roots.
Room 3: beautiful, not a problem, i see a slight bit of too much N but other than that absolutly killer, excellent health
maybe you guys are abletofeed every watering, but its clear to me i cant, if i did my crop would be ruined fairly quick

im sure you cant feed every watering, regardless what the kat said from the US......
its just common sense.....
if i were growing in soil, i certainly would not feed every watering.....
not sure what to say Joe, i just hope that ALL of us can figure out what the problem is.....

whats your run off ppm/ec and ph from those rooms joe?
my guess is they suggest no water between the feeds if you are using drip clean, my plants are getting GH 6/9 every watering and drip clean and run off is same as input and they look very healthy.

runoff in plants that were given feed feed feed was over 2000ppm(4EC), my meter does not go any higher
the runoff of the plants that i was giving water feed water feed was 800(1.6EC) and these plants were in much better health
the other room where the plants are perfect(where i only fed them 1.5 EC every 10-14 days about) i have not measured the runoff because the plants are so beutiful i didnt see a need tobut maybe tomorrow ill do that to get an idea because tomorrow i gotta water them anyways
EDIT: and yes im using drip clean too

when you say you only feed them 1.5 ec every 10-14 days, you are feeding just water in between correct? how often do you water?
i am thinking about trying the soil A & B next round considering it costs the same as using GH micro and bloom cant really go wrong

Thanks, I am guessing your in 5 gal pots or bigger like myself?
Its worth giving the drip clean a try, Like I said earlier my plants are getting 800-1000ppm of feed every watering and with the addition of drip clean there is no build up maybe 150ppm of salt build up at the most.
I am sure feeding less works though, saves money as well so ya can't go wrong there.

Ok, here is what I came up with.
Soil A salt index of 7.64 ( 1.66 SI/unit plant nutrient)
Soil B salt index of 6.4 ( 1.12 SI/unit plant nutrient)
These are probably a close approximation.

During the math, I figured out that they use PeKacid in the formulation of the soil B also

so with a general Si of 7 its a fairly low (Si) nute, actually this would mean that if i am feeding at 1.0EC that would be equal amount of usable nutes to a fertilizer with a (Si) 14 2.0EC correct? or am i missing something?
one more question avenger, since you seem to have a good comprehention of nutes in general....why is my bottle marked with a much much higher npk than the american bottles? i read than nutes with a higher npk numbers generally have a lower (Si) than ferts with a lower number, but there are exeptions ofcourse

its what they use to make drip clean....basicly ....
400G of pekacid powder + 1 liter of water = drip clean
1lb of pekacid = 10$
1 L of drip clean = 60$(around me at least)
Not exactly, but kind of sorta. Salt index is just a relative comparison of the EC any fertilizer will have to the EC that sodium nitrate in solution has.
Each fertilizer salt when in solution at any given concentration(ppm, %, ect) will conduct electricity better or worse than any other salt in solution at the same concentration.
The lighter molecular weight the salt, the more conductive the solution at the same concentration as a heavier salt.
Hence fertilizers with heavier salts like potassium phosphate instead of potassium chloride have a lower Salt Index.

My guess is misprint. Which is why it was taken off the shelf for being mislabeled in Oregon

PeKacid is just a fertilizer salt, it can be used as a component in liquid concentrated formulation like H&G. It is 0-60-20 NPK.

Avenger- From what I understand its not a misprint. It could be B/S but ive been told its b/c some states have tightened fertilizer label requirements. And instead of changing the nutrient profiles they just lowered the %'s on the labels so they wont get fined or taken off shelves.
Also was told when the labels say the N-P-K is
0.3-0-0.3
its really
3-0-3

i don't really like the look of H&G NPK ratio's for Aqua Flakes so for now I'm more interested in good ol GH MaxiBloom and Big Bud as a Bloom supplement gravy

Let me get this straight. You add H&G first. That produces salt in the medium. Then you add their "salt remover".
Maybe I am just dumb ol country boy...but why don't you just stop overdoing the salts in the first place?
This has got to be the stupidest shit I have ever heard.
edit...so first they want you to overpay for salts, then they want you to pay for something to remove it. Like I said, take a fucking class.
