canna PK13/14 is 0-10-11

 

would it be bad to mix professors nutrients extreme boost slightly higher at 1/3 to get 0-18-10.6 ?

 

would the extra P cause problems?

this would work well for clones at clones specific ppms with the higher p for root dev as recommended by a grow book i read.

 

i guess you would have to look at the whole line up of grow/bloom or a + b of professors nutrients vs canna and see if the base nutrients of professors nutrients compensate with extra K, compared to the a+b of canna to see if it is a real different in total nutes combined

I'm gunna give it a try. I got a 500gram tub of professors extreme boost for $40 today. Just flipped 12/12 so it's a good time to test

For anyone in Perth who wants some cheap supplies I know of an ex hydro business now clearing stock out of the backyard.

 

All there nutes are half price.

 

Any sandgropers interested hmu for the details.

been using professors extreme boost @ 1.6g per 60L for all of this flowering, all 10 weeks, fuck it

running at 1/3 strength which brings the PK in at 18/10.6

 

doing the math 500g / 1.6g = 312 / 10 (weeks flower) = 31 grows = 31 / 3 (3 grows per year) = 10.3 years for $40

 

running different plants from when i was running canna PK13/14 so i cannot really judge the difference

Shit my dodgy stoner math failed haha

It's meant to be 0.16g per Liter of water, I was basically giving the plants basically no extra PK

 

Fixed it and within 1 day they all threw heaps of new bright white pistols

 

Full strength mix ratio is 2g per 4L = 0.5g per L

For a 60L res the math works out really well

 

0.5 / 4 * 60 = 7.5g - 1/4 str - 0-13-8

0.5 / 3 * 60 = 10g - 1/3 str - 0-18-10

0.5 / 2 * 60 = 15g - 1/2 str - 0-27-16

0.5 / 1 * 60 = 30g - full str - 0-54-32

 

10g divides really nicely into 1L bottles

100g per 1000ml water, this gives 1g per 10ml

 

75ml per 60L - 1/4 str

100ml per 60L - 1/3 str

150ml per 60L - 1/2 str

300ml per 60L - full str

 

I'm just going to run it 1/3 str for 3-4 weeks per run

 

Going on 100g makes 1L means a 500g tub makes 5L

 

5000ml / 100ml = 50 weeks worth

50 / 4 weeks per run = 12.5 runs

12.5 / 3 runs per year = 4.1 years

 

$40 / 4.1 = $9.59 a year or

$40 / 12.5 = $3.2 per run

Just read a bit more about the product. Did you honestly notice it making a difference?

PK13/14 makes a difference, everyone agrees already

I dont think Extreme Boost would make a massive difference the way they advertise it

Diluting it and using as a PK booster is what I'm doing

When I used the correct 1/3 dose, the next day I seen new bright white pistols everywhere when they were turning brown, they are grown more since

[pedro de pacas]

No tnuc knows when to use it tho

No tnuc knows when to use it tho

Could just run it all 8 weeks at 1/3 str 0-18-10

 

A $40 500g tub would last 2 years

 

PK boosters crack me up. I understand why soil and semi organic folks use it during bloom but I don't understand why a hydro bloom nutrient would be short on PK in the first place. It's suppose to be a high PK mix.

Most Bloom A+B are around 1-5-4, if you want high PK you need a booster

All lines recommend a PK13/14 booster ranging from 2 weeks to the whole grow

 

It's cheap and works, no reason not to use it
