I'm sort of wondering how this thread became a I have no idea how to formulate, can you help thread which dilutes the great information which was posted here years ago.


And to answer that - look at it this way, if a company lists accurately they give their formula away to any half arsed formulator. Would you list accurately if this were the case? Then of course there are the garanteed minimums and compliance testing by agricultural regulators so you always list lower than is in the bottle to ensure any discrepencies don't fall below guaranteed minimum.

Nice to see someone who just shows up and starts acting like a dick to folks. Regardless of who knows what your the kind of douche that must make friends where ever you go. I predict banishment for thee in in a short time.

Sounds more like he showed up and gave a dude some info and was treated disrespectfully, and responded in kind.
Kind of how you mouthed off to me once for no good reason, so I have to laugh at your white knighting

Lets get back on topic. The "High P" in the thread title does not stand for "Pissyness".

So if high P demand is a myth, then what is the minimum requisite amount of phosphorus? What exactly constitutes "too little"?

Post #51 is very informative. Read what YosemiteSam says starting on page five.

From my own experience I wanted to see how low I could push P. In veg I was around 27-30 ppm and starting 12/12 I increased P to 40 ppm. Around week 5 1/2 into 12/12 the plant leaves didn't look as lush as they should. I didn't see any difference in flower size or appearance. At that point I upped the p to around 80 ppm for a couple weeks then reduced my EC the final 10-14 days till chop.


@ OMalley
Great job learning how to break down nutrient profiles. There are several Dept of Ag sites from various states that randomly test fertilizer and post the results online. I'm glad no one was around telling me that breaking down nutrients is just a waste of time. It's given me the ability to tailor my nutrient profile as I see fit. For 40$ you can send in any fertilizer to a lab and have them test it for macro and micro nutrients.

Cheers

I'm into this topics since a while and i'm at the point where i'm really convinced that higher amounts of K (Potassium) and Mg are the things that could be used as a booster (without the P in PK Boosters)

I was thinking about to accomplish this with potassium (20% K2O) from the CANNA mono line and some epsom salt when stretching stopped and the first buds formed.

The thing to solve at the moment is figuring out how much K is too much and results in toxicity or Mg lockout in conjunction with the lucas formula.

What do you guys think about that?

Planned schedule would be:
Flowering
week 1 - 3 lucas 8/16 & Bloom stimulator (just stimulator w/o nutes)
week 4 - 6 lucas 8/16 , Bloom stimulator, + K and Mg supplement
week 7 - (8,9) back to only lucas + stimulator
flush

i dunno if this makes sense but it seems like a simple working formula for me.
maybe i'll supplement some chitosan and molasses inbetween but i like to keep the things not too complex

Good to see the thread getting on track and therein lays a very good question. There is no single right anser though if you look at the science because grow methodology and fertigation frequency come into play. So as an example you may be talking say 80 - 90 ppm if you were only feeding the girls once a day but if you were feeding 8 times a day (high fertigation frequency) you may be talking 30-40 ppm or even lower because by feeding more you are more regularly supplying P to the root interface and vacinity where it is then available for uptake. One thing is certain, if you look at all dicot plants including herbaceous dicots the stated to be ideal ppm of P is vastly lower than hydro manufacturers recommend when you break down their feed charts. What is certain is most hydro manufacturers don't know crap or they simply want you using rediculous amounts of their PK additives so they can line their pockets (while likely losing us yields because excess P and K results in lockout of other key nutrient ions such as Ca and Fe).
