It could work, though the SPT isn't very high in nitrogen and you do need a little during flowering. A little potassium wouldn't hurt either assuming the High P guano they sell doesn't have any, I can't really recall. You could try it and if you see any problems occuring, get something with a little nitrogen. Though it is normal for plants to use the nitrogen from their fan leaves during flowering causing them to yellow and die off but its still best in my opinion to give it a little nitrogen.

Nah, this won't get you by for flowering. Plants need a little N and a little less or the same amount of K as P during flowering. I'd highly recommend getting Peace Of Mind Bulb Food 3-8-8. Great stuff and is all organic, made by the guys at Fox Farm. That has the perfect ratios and can be watered right in.

thanks guys for all your input ....makes perfect sense to add some nitrogen cause i do have some leaves that are yellowing a bit ....i also have high N guano as well so ill add alittle n next time around see if that can help any.....my nutes are-high p guano,high n guano,super plant tonic,floralicious plus

Don't go too crazy with that high n guano during flowering. Plants during budding don't need large amounts of nitrogen. a ratio of 3 is perfect for vigorously flowering cannabis plants. If you give them too much nitrogen during flowering they could stop budding and start VEGGING again! Growing further between node spaces and branching out more.

very true and im giving them at a dosage of 75% less then recommended thanks tho for your input

to serve man, dnt kno how ur plants wud revert to veggin cus of the nutes matey unless u flipped em off 12/12 they are goin to bud, nw his product may nt smke 2 good bt its still buddin whoever or whatever led u to belive that crock was wrng pally

It will grow a plant yes. but not high grade herb :[
You are better off growing grandmas tomatoes with that...

You can definitely grow cannabis plants using primarily guano. One of the only major things that guano lacks is soluble K - potash.
A side note here is the way that natural\organic fertilizers are labeled; the NPK ratio may only figure in approximately how much soluble or available K the product contains, not the actual or total K. Greensand, for example, releases relatively minor amounts of soluble K over the long term (we're talking years), but may have a total K content between 3-6%. For nitrogen in particular you will most typically see a ratio\breakdown of soluble to insoluble N, but this often isn't the case for phosphate and potassium.
Otherwise you can mix different types of guano to get the N-P ratio you desire. When I have it, I generally rely mostly on Peruvian Seabird Guano (it is thee shit). PSG is about a 10-10-2, so in veg I would provide it in conjunction with a high N guano (Mexican 10-2-1) and in early bloom I'd give it with another high P guano (Indonesian 0.5-12-0.2 or Jamaican). Midway through it is all but replaced by a strictly high P guano.
Say I use a tbs of Peruvian and a tbs of Indonesian (equal amounts): I now have a 5-11-1 (roughly). If I used equal amounts of Mexican to Peruvian I'd get 10-6-1.5, and say I added to this a tablespoon of blackstrap molasses - which we'll assume is 1-0-5 - my resultant NPK is roughly 7-4-3. The nitrogen value is a total of soluble\insoluble, while the P\K is strictly soluble.
But again, it is important to remember that guanos contain more than just nitrogen, phosphorous and potassium. They are also rich in micro-nutrients\trace elements and the material is biologically active (it has microbes). It is also much easier to over-do guano than low-NPK organic bottled nutrients. If you have a healthy, well-prepared soil you shouldn't need much else other than guano. You can load your soil up with greensand and kelp meal (use only recommended rates of kelp products) to fill any gaps, irrigate with molasses (more K and trace) and make sure you have dolomitic limestone in sufficient amounts in your soil (for Ca\Mg and neutralizing pH). It also wouldn't hurt to keep a high-K bottled nutrient around (such as Meta-K, 0-0-10) and perhaps a micro-nutrient supplement.

Would seaweed extract be good for potassium?. I've been using one from growmore in my compost tea that has an npk of 0.1- 0.1 -1.5. I got some indo guano for the pk bump in the 4th week. i just grabbed some other seaweed extract that has an npk of 1-1-16. I plan on doing that half strength

good guano has P & should be used during the vegetative period becouse the plant asmilates the p from vegg and use it on flowering time. P takes too long to assimilate. its a common mistake in most growers. waht you need during flowering is K and N at the begining. the P must be used since seed and all throw vegg until it starts flowering. in vegg you need P & N. (only talking about macronutrients here). becouse the P form the structure of the plant, N is for the green parts and K is for flowers.

this is opinion bro, its a common mistake from most growers (maybe a 90%), if you dont believe me, then try this in one of your plants:
feed from the start with P&N (mostly N) then, in flower, dont feed P and feed N&K (mostly K) see what happens

That had to be the dumbest shit i ever heard. To much nitrogen doesn't put a plant into veg it just kills the fuck outta the plant. I've seen it more than once.

You really need to know your soil...mine is very high in K..and low in N..SO I DO A INDONESIAN bat guano 50%(8cups) Seabird guano 40%(6 cups) kelp meal 5%( 1 cup) Molasses 5%(1 cup) in 30 gal trash can...i make tea with air pump for no longer then 24 hours you will see it cooking...Then i water it in at about a 50 to 1 rate...But this is after all the soil prep that starts after harvest..Clean out chicken house put in garden plant cover crop. Then i feed soil two times one time when i till up cover crop to help brake every thing down and then when i plant to feed plants, i fertalize with teas threw out the grow season So you see there should be no shortage of NPK because all that Organic stuff brakes down at differnt times and lots slower then chem fertlizer...So you should have a slow steady feed threw out the whole season and sort of ending at harvest..I stop feeding a month befor harvest just molasses till the last two weeks then nothing. just water. and very little of that.....Thats what i do hope it helps.

WOW!!! It's not opinion its fact. Read any horticulture book. horticulture 101, 102, and 201 from University of Missouri are the best ones. Also Microbiology by Dr. Elaine Ingham or Compost Teas by same person, or even anything from Oxford Journals. My question before was rhetorical,.
Read A Book before making stupid statements !!!

Why you need to desqualify me calling me stupid?. The plant catches al the P given in vegg & then uses it during flowering period. You dont need to feed P during flowering, it wont assimilate it. I wont stop until you try it bro, just try it in one plant cmon
youll realise who the stupid is

I call shenanigans. You are still wrong.
P helps with the photosynthesis during veg. During flower P helps with flower production and respiration during both.. P is a mobile element. If you don't use P during flower, you will have small shitty buds. Every type of plant needs P for flower production. You need to back up what you say with scientific proof. otherwise its just nonsense.
I have a buddy who is new at this and he didn't give any base nutes during flower. Only a low npk compost and great white and karma. His turned out small and and airy and not that great. Mine of the same strains was way different. mine were bigger, much prettier, and more potent and way more trichome formation. He was lacking P and K. So I guess that's the experiment you want me to try. That helps back up what me and the rest of the educated world does.
The only reason I called you out is because I don't want anyone to waste time and money following bad advice. Your like the guys at the hydro shop. Buy this it will make your plants blow up. Oh that didn't work well spend more money and try this. Oh that didn't work either ok then ........
