Will this work

i don't understand his endgame? if he used floranova and it didn't work because of multiple deficiencies, then i'd understand. but to have never tried it and claim that it wont' work seems weird.

surprised he isn't recommending mercury vapor lamps that were invented in the early 1900s too. lol.
I said I did use it and got better results when I switched to MaxiGro. I was always getting leaf burn and low yields from FN Bloom. Not anymore, thanks to MaxiGro. 1.5 g/L and I'm good.

i missed that part. have you also tried maxibloom? i don't think you can get much cheaper than dry nutes.

I personally get higher yields using GH MaxiGro for all stages than I did with FloraNova Bloom. They also have a MaxiBloom but I don't use it.
He speaks the truth. I totally missed this for some reason. Sorry for being a dick bob! Still gonna go with floranova bloom though since i already bought it. Maybe ill try maxigrow next. Cheaper is good

@cannn if you want to try powders next, maxibloom is the one to try. it also closely follows the Lucas formula.

79/104/184 per 6g/gal is pretty damn close to 100/100/200 of Lucas formula

My intention with trying maxigrow was also to see for myself whos right. As much as Bobs phosphorous ratios make no sense to me i dont want to just dismiss it. He must be using it with some kind of results to have taken this so far. That said i know another grower around here who does hydro and his bud comes out all wrong and he always thinks its the shit so im always doubtful. It always looks like he harvested super early and gave too much n didnt cure and quick dried but you could never convince him hes not growing the best there is

Thanks for the info though, ill keep that in mind.

i'd be curious to see if he supplements with something. that just seems way too low P in my opinion. his results may vary though.

i dont' see how that ratio works at all for flowering.

159/35/184 ppm NPK per 6 g/gal.

every bloom recipe i've seen has 80ppm P minimally during bloom

are you using any PK supplements? or just maxigro?
Well so much for the bloom recipes then, because my plants definitely flowered plenty. There is no "flowering formula" in real hydroponics. It's the same formula all the time. Here's a good page about it http://thcbiomed.com/topic/the-origins-of-liquid-based-concentrated-fertilizers-hoaglands-solution/

Interesting quotes;
Hoagland’s solution was not designed to be applied in different ratios, such as a “veg” or “bloom” fertilizer, one standard dilution was good for all plants. The 4-part stock solutions were conceived to prevent the chemicals involved from cross reacting to produce insoluble precipitates, and when mixed the same way they created a reliable and constant fertilizer solution. This link describes the preparation of Hoagland’s concentrates;

http://prometheuswiki.publish.csiro.au/tiki-index.php?page=Hoagland's+nutrient+solution

Cannabis plants require all 12 mineral nutrients that are found in Hoagland’s formula, and will grow well when provided with the amounts found in the 4 concentrates. But this is a generic, one-formula-fits-all-plants approach that is better suited for laboratory growing. There are some cannabis-specific fertilization strategies that are known to produce superior yields, one of which is to stop using fertilizers at the end of the crop cycle. But throughout the vegetative growth phase and during blooming there are cannabis-specific things to consider with regard to fertilizers.

A cannabis specific nutrient regimen would be identical to Hoagland’s formula but with higher amounts of Calcium (Ca), silicon (Si), and potassium (K) to enhance cannabis flower development. No nutrients are limiting with Hoagland’s formula, but extra Ca and Si help build the cellulose and cell walls in between plant cells. Trichomes, the transparent resin glands on cannabis flowers, are made mostly of silicon and calcium carbonate so Ca and Si should be abundant in the soil when plants commence blooming.
Maybe I should use the silicate more. I have it but didn't really use it other than maybe in early flowering for stronger stems. If it's needed for trichs then maybe I should use it all through flowering. I don't think there's any need for extra calcium though. They should get enough from the stock solution.

not necessarily. look at the works of mel frank, MJ growers handbook by pH imbalance and others. they have different NPK ppms for all stages of growth, veg and flower. http://www.angelfire.com/cantina/fourtwenty/articles/profiles.htm

i know you are hooked on hoagland but that was a specific formula for tomatoes for 1 week during heavy fruiting.

let's break it down just for bloom phase: they use tons of N during stretch then it drops. they use tons of P during onset of flowers and then it drops. they use tons of K to increase weight of flowers at the end. hence some people using a PK boost right after stretch and at about week 6.

from your article: There are some cannabis-specific fertilization strategies that are known to produce superior yields,

and just to clarify, all you use is maxigro from day 1 to chop?

Yup, MaxiGro all the time. Never tried the MaxiBloom. It's the same idea as the FloraNova Bloom so I didn't want it, plus it has a reddish dye added. The gro is white powder and clear solution. The only thing I don't like about it is that you can't pour it or handle it roughly or a lot of chem dust gets in the air, you see a cloud of it.

well, i would have bet money you had to use something else in bloom like koolbloom or similar along with the maxigro.

ain't growing fun? always something new to learn.

My suggestion is to try it and see. All I can say is it works fine for me and I like the fact that it comes in bags, which are easier to get rid of inconspicuously than plastic bottles.

I use the flora nova grow and bloom with good results. I was just wondering why you suggest to use fn bloom from day 1 and never use grow.

Does the grow cause deficiencies or is it just for the plain simplicity of only having 1 bottle for start to finish

Yeah this is a good question. Idk why i never asked it

Kinda just went with it since it sounded so simple

yep. you could probably tweak the bloom with a bit more N for veg phase if needed but as is, it's a start to finish 1 bottle nute.

KISS- keep it simply simple
How do you figure that, with only half as much N as P and K? Is low nitrogen supposed to be good for vegetative growth? You could buy some potassium nitrate separately and add enough to bring up the N and K parts and you might be okay. You can buy it in pharmacies as saltpeter. At least you could before the terrorism craze. Haven't looked recently. From google it looks like it's N-13, K(K2O)-46 as fertilizer, so kind of low on nitrogen actually. Oh well, you need more K than N anyway.

when used at 8ml/gal, you get 100/100/200 npk which is 1-1-2. many growers prefer a 3-1-2 mix for vegging. 1-1-2 is adequate for most strains but some are N hogs.

you could just add cal/mg to bring up N too.
