i dont know much about what would happen if you fertilized with this mix, but the reason behind having a npk of more P is to have bigger buds. N stays out because it doesnt need it anymore.........but K? where does he fit in? its hard to overfertilize with it right. does it matter that theres more K. i see that N is virtually nonexistant, so thats why its called "big bloom". i ordered and already received this fox farm product and am hesitant to go with my instinct to go with "tiger bloom instead". but now, because of what research ive done on this i thought since i live kind of far up here that the extra P would help with the colder weather later on. i got little info on why the extra potash and am very interested in hearing the answer to this . no biggy, just want some technical info. thank you.

This belongs in the Plant Food & Nutrients forum for obvious reasons!

You mean potassium (K) ? That is a high ratio, though I've never used the stuff. The tiger bloom 2-8-4 has a good ratio, you want a considerable amount of P and a little more K than N, at least according the reading I've done...

Well Potassium is there to keep your plant healthy. Potassium(hope I'm spelling that right) is the nutrient that gives your plant strength to fight disease. So it is great to have in there.. however if you are flowering you want to get a higher concentration of Phosphorus (P), which you are in luck... because most commonly sold fertilizers have the higher concentration of P. Miracle-Gro Bloom Buster fertilizer has a ratio... something like 10-52-10! Wether this is particularly good for Cannabis, I'm not sure about that.

just for the record i meant K not P. i read that its good for staying healthy in cold temps. if someone knows the answer to why theres so much more K please...im very interested.
also see how its so unconcentrated? i know that all organic ferts are supposed to be like that but are they as effective?. it says that its an alternative to chemical ferts. im thinking that the only reason it gets as much attention as it does is because its so good for the earth. it says its 100 percent organic. but my main concern is the potassium.

Fox Farm Big Bloom is supposed to be an excellent fertilizer, but I have no explanation for why it has so much K in relation to N and P. I probably use more K than most people but not more than N in vegging or more than P in flowering. I also don't know why it's so diluted. All organic ferts are not that weak. Common organic ferts are fish emulsion (5-1-1), blood meal (12-0-0) and bone meal (6-12-0). Big Bloom contains earthworm castings which are great, providing micronutes, beneficial soil bacteria, enzymes, etc. but you would have to use quite a bit of this fert to get much NPK value. In fact the package directions say to use 1/2 cup per gallon of water the first time and four tablespoons per gallon every watering after that. This is a lot stronger than most other ferts, including organics, are applied.

High potassium in plants can help maintain health and protect your yield under moderate drought conditions by increasing your plants stamina.
When plants are faced with drought or high heat conditions, they move potassium into the leaves to close the stomata (like pores on the leaf), thus reducing transpiration (loss of moisture).
Potassium also increases the strength of the individual cell walls, and is helpful during light frosts- it's the rupture of cell walls that cause freeze damage.
K is also asscoiated with nitrogen assimilation.

I mainly use potassium via liquid kelp as a foliar feed on my outdoor plants during high heat, low rainfall, or other stressful conditions.

im not as knowledgeable as id like to be on this subject, however i can say that i myself wouldnt use that ration on my plants. that is unless i were right inbetween veg. and flower and i wanted to experiment or something. it seems like a flowering type fert. what stage of growth are you considering for the use of this fert? theres two main stages of growth. veg and flower. for veg use a bit more N thanP and K. for flowering use much more phosphorus than the two.:ironyeople experiment using lots of different ratios in this area but not really like the one your asking about. i could be wrong but i wouldnt recommend it. many use 20 20 20 for both stages and have good results. take a look at the grow guide. its a great summary of mj cultivation and it probably has all the info you need for right now. youll learn a lot more in a shorter amount of time there than you will here.

When I first started researching K & its benefits, then applied a 2-1-2 veg instead of the commonly suggested 2-1-1...my stems thickened dramatically and overall growth much more robust. The exact function of K in plant growth has not been clearly defined. Potassium is associated with movement of water, nutrients, & carbohydrates in plant tissue. If K is deficient or not supplied in adequate amounts, growth is stunted & yields are reduced. Various research have shown that potassium....
* Stimulates early growth
* Increases protein production
* Improves the efficiency of water use
* Improves FROST resistence and
* Improves resistence to diseases & insects
So to bombard the plant with N & little or no K will cause a K deficiency, where smaller amounts of N would not. N just might be an over-rated macro anyway. btw~ Some of the newer tomato food formulas are higher K..such as Schultz Expert 9-10-15..which would break down to a 1-1-1.5 ratio but with mj in flowering N should be no more 5%..blah blah
