NPK question

Hey Y’all,

I was recently watching a couple grow journals from Greenhouse with Arjan and Franco(RIP Franco) and they talk about feeding a 1-2-2 NPK in flower with an EC of 1.8. Im curious of a few things here...If these guys are using an NPK of 1-2-2 and showing great results, then why does everything on the market have suck high PK for flowering? Am I missing something here on how to actually figure out NPK of combined nutrients? Can a nutrient mix containing a 13/14 boost still, after dilution, equate to the PK of 0-2-2 if mixed in RO water?

It's about the ratio, not how big the numbers are. So a 1-2-2 is the same thing as a 10-20-20 just need to add more of the 1-2-2 to get the same PPM.

Check out the calculator in my signature. What you really wanna know is the elemental PPM of each nutrient.

Thanks for your reply Man. I don’t see a calculator in your signature. Can you link to it?

I can see this being true

its in the nutrient PPM thread

Low nitrogen so they can overdose you on pk without killing you with nitrogen.

They sell bottled orange peel extract as terpene enhancers for fucks sake.. Get out of the hydro shop. Its a SCAM

yeah pk 13/14 is 130gram of p2o5 and 140 gram of k2o mixed with 1 liter of water if i remember
so yeah 10-10-20 Is ten times more concentrated than 1-1-2

if your are talking hydroponic i would stick to 4-3-7 for bloom .. and add a pk booster of your choice ..
1.8 mS seems a tad too much for me, i would stay around 1.3 for bloom

not sure to understand
are you saying 1 1 2 and 10 10 20 are the same ?
or my ratio are erronated in your opinion

Yes 1x10 = 10 , 1x10=10 , 2x10=20

10 10 20 just has more parts per million of NPK in the water. So 1 1 2 is more diluted, watered down etc

there was another comment but i disappeared like magic
