ppm?

[blu-hash]

I'm using flova feeding system micro,gro and bloom the chart I have says for my ppm to be 800-1000ppm and mine is only 530 gave it all the right amount of nuts and today I noticed my ppm goes down and my ph will go up now my ph is right and my ppm is still low any advice will help thanks

Re: ppm ?

If it's calling for 1000PPM you must be in the recirculating hydro setup, as the drain to waste is 800 PPM max.

Are you mixing micro first, is your PPM meter new/calibrated, are you reading PPM before feeding?

 

[blu-hash]

Im using a bubbled dwc and yea I read my ppm its around 200 ppm

 

[JJ Bones]

Your PPM meter is calibrated correctly? Are you adding micro first?

 

[blu-hash]

Yea its calibrated correct checked it 3 times I use micro first then gro then bloom what would couse my ppm to keep dropping

 

[JJ Bones]

I wouldn't be considered with PPM dropped, that means plants are intaking nutrients.

I'm confused why it would be so low to begin with if you're mixing the recommend ratios at full strength?

 

[blu-hash]

Or what can I do to bring my ppm up my ppm right now is 573 and my ph is 6.71

 

[JJ Bones]

What ratio per gallon are you mixing

 

[blu-hash]

There on there 2nd week and it says 180ml micro 80 ml of gro and 50ml bloom

 

[JJ Bones]

Per gallon?

 

[blu-hash]

All togather my chart has it were I put in how many gallons I have and it converts everything u can check it out its Flora Nutrient Weekly Feeding Program - Greentrees Hydroponics

 

[JJ Bones]

That source you're getting the nutrient schedule seems off, I'd stick with the manufacturers information.

Feedcharts

Ok thanks for ur help

Also you should consider that different sources/people use differnet conversions of EC to reach their ppm's.

One of the problems with converting with Growers in different areas and with different equipment is that CF/ppm/EC meters
express different yet very similar measurements. All effectively say the same exact thing it's just a case of what measurement is used

The two levels expressed at either end of the columns are the generic measurements of CF and EC and the center 3 column express the different PPM equivalents for the 3 most popular meters used internationally

EC Hanna Eutech Truncheon CF
ms/cm .5 ppm .64 ppm .70 ppm 0

0.1 50 ppm 64 ppm 70 ppm 1
0.2 100 ppm 128 ppm 140 ppm 2
0.3 150 ppm 192 ppm 210 ppm 3
0.4 200 ppm 256 ppm 280 ppm 4
0.5 250 ppm 320 ppm 350 ppm 5
0.6 300 ppm 384 ppm 420 ppm 6
0.7 350 ppm 448 ppm 490 ppm 7
0.8 400 ppm 512 ppm 560 ppm 8
0.9 450 ppm 576 ppm 630 ppm 9
1.0 500 ppm 640 ppm 700 ppm 10
1.1 550 ppm 704 ppm 770 ppm 11
1.2 600 ppm 768 ppm 840 ppm 12
1.3 650 ppm 832 ppm 910 ppm 13

sorry that didn't copy and paste well... Essentially EC is the electric conductivity of specific salts in your soup... ppms are derived by converting the EC to ppm's through an equation that are not the same with all ppm meters... The three most common conversions are .5, .64, and .7. From what I understand.

Just be careful following recommendations of ppm and make sure you are using the same conversion.

That's good info.... i personally know nada on "ppm" and some off your words are new to me. Is there a way I can do the equation w/out a meter? and when adding for Ph i use General Hydro when i use test tube i get Ph to my level what equation would b equal as far as my 6-5 gallon buckets, say 20 gallons? the chart says ...=1 gallon. I tested today and may have killed em by making (-) ACID low then just as much base +.... to counter act...HELP?!?
