Advanced Nutrients - Sensi Base (phPerfect) - Dosage

Hey guys.

I have a question for somebody using the new ph-perfect base nutrient Sensi Bloom A & B.
I mixed the base nutrient & all suggested additives for my current bloomweek. I've used the recommended dosages for their products and :clap: i had to laugh when i measured ppm values because they exceeded a value over 2800 ppm.

So I started to mix around and my goal was a ppm value of 1200 ppm.
I noticed that i had to modifiy thes dosage for all additives (1/3 of the recommended) and of the base (1/4 of the recommended) to get a common ppm value.

I made a few tests with 3 different ec meters and my values were: (Sensi Bloom A + B without any additives, just the base)
1ml/L
610ppm
2ml/L
960ppm
3ml/L
1450ppm
4ml/L
1800ppm

The AN support told me that it should be
1ml/L
300ppm
2ml/L
600ppm
3ml/L
900ppm
4ml/L
1200ppm

and they blamed my ec meter for the different measured values.. ^^
now i told them that i used 3 different ones, and that i took 3 samples for each dilution (to be sure that i didnt do any mistake) and that i got the same values i measured with mine own and now they dont write back anymore xD

Now i am wondering what kind of dosages do you use for Sensi Bloom A & B?
I am sure 4ml/L will kill my plants ;) As said i use 1ml/L to get a common ec + 1/3 of the recommended dosage for the additives.
I tried to use 3ml/L and that gave my plants some nutrient burn. (3rd week of bloom)


They also send me a feeding schedule (because i said that the online calcultor is messing around with values).
I mixed additives & base together (as the schedule said) but i measured very different ppm values then the ones given by the schedule.. ^^ :clap: (much much higher)

They also told me that Sensi Bloom isnt recommended for growing in coco.
And after 5 mails i still dont know if i need to bring the ph of my (phperfect) nutrient solution down to 5.8 (a common value for coco), because without adding phminus the ph values are between 6.8 and 7.3 (wich wouldnt be a common ph for coco)

Hope that someone here can help. I am from europe and nobody here (i already asked many growing comunities over here) could answer my questions so far ^^

Well If you look at their dosages they go up in equal porportions, 1ml=300,2ml.=600 and so on. If you know anything about chemicals it is impossible to gain ppm as you increase volume. 1ml should gice you the same calibration values as 10ml's.

Are you reading you water solution before you water or your run off? What are you using to measure with? I have used all their line of products and have never found my numbers that far out! Something is not right for sure. Do you shake your jugs up? Everytime?

By your explaination I would have to say its not the nutes and maybe something enviormental or mixing problems??

Never seen this before. If those numbers are acurate I would use it 1/2 to 3/4 strength and keep an eye on your ppm. 1200ppm is more than enough of any AN product for mots cannabis strains.

I did notice the thing with the proportions and i cant explain the fluctuation from 2 to 3 ml.
(thats the first thing that i noticed xD i am studying biochemistry) I thought that this could be due to some reactions of the nutrients with my tap water? (but i dont think that the fluctiation would be soooo heavy, my tap water has a ppm about 160.

I am reading both values (solution before watering and drain).
I measured with a Hanna Grocheck and bluelab truncheon (i dont trust the hanna thing^^ - but it shows the same value as my truncheon)

The support guy told me also thats its very uncommon..
I just can think about 2 things which might cause this problem...
1. my tap water
2. old non ph-perfect nutrients in new ph-perfect bottles (my ppms are matching with the old calculator oO)

I always shake the bottles before taking nutrients out.. Maybe i should shake stronger and make another test ;)

To be completly sure about my measurements, i will make another one with another ppm meter ^^

so its not common to get such values with this nutrient?
did you measure the ppms values?
i would like to see somebodys measured values for the dosages, to be sure that something is really wrong here xD

now i measured with ro water and i got results without fluctuations
but, ppms values are still way too high

with RO
1ml/L --> 570 ppm
2ml/L --> 1140 ppm
3ml/L --> 1710 ppm
4ml/L --> 2280 ppm

can somebody tell me if my measured values are matching with the dosage of the old sensi bloom (non ph perfect)?
i believe i got a new bottle with old nutrients inside.....

Thanks for passing on the dosage instructions to those who aren't sure how to make the switch to pH Perfect nutrients.

I'm not sure why you're still having issues when you're following what the pros said.

my schedule works very well ;) i will post it here

i was just wondering how AN can recommend a dosage which is soooo high and i dont believe that this shit (full dosage) would work for anyone ^^
So its bullshit that you can mix without a ppm meter xD i would never ever have the balls to do so ;)
the ph perfect thing seems to work. i am not adjusting the ph of my nutrient solution, even not measuring now (should be around 7, when i add oxygen stones it tends towards 8, i read that ph perfect works to a range of 8,5 - i hope so ^^)

once a week i do flush my coco medium with phed water (6.0)

Hi prinzpinky, I just joined this site to reply to your post. I too am having probs with the Ec (ppm) using ph perfect and all the addatives. I use reveres osmosis water so start with a ppm of 0. I followed all the instructions for the first week of flowering (not hard!) 4ml a+b seni bloom per litre and 2ml per liter of the stated addatives, quite a few as im following the grand master plan. The ph set great 5.6 (sweet spot) but the ppm was 1230 i expected around 700. Its easier comparing EC values than ppm As north America\canada use a scale of 700 parts per million for 1 EC where England and most of europe use a scale of 500 parts per million to represent 1 EC, either way 700ppm (north america) or 500pm (europe) = 1 ec.

Just working in ec though my mix works out at 2.5 ec there site states 1.4 ec, mmm bit of a descrepancy.

I have sent an email to a\n but am still waiting for a reply, ah well guess it serves us right for buying the cheapist nutrients, lol :(

I also noticed the same thing with Sensi A+B Bloom (old bottle) I bought 4L of both and 4ml/1L is way too HOT :D 2ml with all the additives is still a lil bit hot.
Might be some mixing problem at the AN factory ? :)

make sure to shake the shit out of your bottles too, if you get a chunk of mineral salt it will really mess with your ppm, also make sure your water is mixed well and had a minute or 2 to rest before testing. I used to use General Organics BioThrive lineup, with all the extra calmag and crap on the side, and my ppm was never the same, always had burn or lockout, ph was all out of whack no matter what i did. I switched to Advanced Nutrients. I have used the 2 part Sensi Grow/Bloom PH Perfect, and now am trying the 3 part grow.micro.bloom php. It is so much better than the organic nutrients that a comparasin doesnt even seem fair. I have NEVER had a PPM or PH problem with the AN. I just use regular tap water (ph around 7.5 avg). I use 2ml/L, maybe 3ml if its a big plant and thats it for veg.
Blooming i have been using the PHP Connoisseur with bud candy for blooming. No deficiencies and they are growing nicely. I used Bud Blood and Big bud, with some Carboload for the first 2 waterings after the 12/12 switch and it really did speed up the veg-flower transition.
For autos, i give no nutes until they start to show pistils, then only 1/2 strength veg nutes every 2nd watering, with bud candy as well.
check out my 15 strain grow i have going now.....Its all using Advanced nutrients PHP. Promix HP soil. Perlite.

I used em at quarter strength in dwc buckets.. Was less then stellar nutes though IMHO.

I tried the AN in DWC too and was not impressed.
Advenced Nutrients PHP is definitely superior nutrients for soil applications i found. And the Connoisseur rocks.
I want to try hydro again sometime, last time i didnt quite understand PPM and just all the upkeep and whatnot on the water lol. killed a chocolope kush :-( Since then i have over 40 more plants under my belt from my 4x4x7 and 2.5x3x7 space.

14 ml A & B (Sensi)
6 ml BudCandy
6ml Big Bud
6 ml Sensizym
6 ml B52
6 ml Nirvana
