Tomato fertilizer in flower. Ok or no?

[Penguin59]

Hi all,

I've started growing organically in my current grow and have been feeding my girls nothing but pure water all along. They are now in their second week of flowering and look to be very green and healthy still.

Was debating giving them a bit of a helping hand though and bought the below product to beef up their P & K ratios. Could someone please take a look at the below product that I picked out and let me know if it will be ok to feed the girls with throughout flowering?

yes, this will be FINE! just about perfect actually!

is this an Australian product? guaranteed organic?

cheers!

 

[Penguin59]

Hey Sat X RB!

Cheers for the reassurance friend It is indeed an Australian product but I don't think it's organic. I won't be too fussed if it adds a bit more weight to the girls though.

Have tried most of the canna specific nutes and tomato ferts are comparable and cheaper , in soil/compost and outdoors , not so good in hydro.

That NPK ratio looks fine but you might see the benefit of more Mg , none of the tom foods i tried had enougth for bud or even tomatoes.

IMO get a 5 gallon bucket fill it half full of luke warm water add potato peels , orange peels banana, egg shells more or less table GREEN scraps stir it up while keep adding little water every day in less then a week you will have over 2000 ppm of nutrients screen it out add 1 cup of it into 5 cups of fresh water or if you got ppm meter / ec mix accordingly.

Hey foomar and DrFever! Thanks for stopping by and for adding some great advice.

From what you've all said here I should be fine with this fertilizer for flowering. If I wanted to go 100% organic in my grow I would definitely go with DrFever's organic recipe above. You guys must be doing something right as the links in both your signatures are bangin'! haha

That fertilizer looks good for veg growth but I wouldn't use it for flowering. With an 8-3-10 npk ratio it has too much nitrogen for flowering and too little phosphorus. Try a blooming-flowering fertilizer with low nitrogen and high phosphorus. What you have would keep the plants alive but it's not ideal for flowering and will probably give you very green leafy buds.

Hey s00thsayer!

Thanks for the input friend. I will maybe try to hit up the hardware store soon to find a fertilizer with a higher P & K rating with a lower N rating. This tomato one was the best I could find the last time I went. The other ferts there were either 24:12:10 (ie. N way too high) or 12:1:12 (ie. N & K but no P). This one seemed to be happy medium.

Will keep you posted if I find something else.

Not organic...EDTA Chelate process is horrible for the beneficial bacteria and environment...

Hi Neo 420, I'm not familiar with EDTA and had never heard of it before but I quickly checked out your link and it seems that it is indeed not an organic compound.

In that article though I also came across a couple of citations that seem to say that its application as a fertiliser should be ok:
"EDTA has antibacterial activity and metal chelation of the ligand reduces this activity"

I believe that where my bottle says it contains Manganese and Iron as an EDTA chelate means it should be fine as the EDTA has bonded with these two metals, thereby reducing its antibacterial activity.

Also, "The interaction mechanisms of EDTA with living organisms are not sufficiently clarified and the range of their potential risks is not known." Not sure if the term 'living organisms' in this context could be related to plants but if so, they will need to do more research on the issue to find whether it is indeed damaging.

Please feel free to correct me if I've misunderstood something here.

Look for fertilizers for growing roses or orchids, something with around a 1-3-2 npk ratio so it has two or three times as much phosphorous and potassium as it does nitrogen or if you can't find one an all purpose fertizilizer with equal parts of nitrogen, phosphorous, and potassium would work better than what you have. Don't get super bloom fertilizers because they have way too much phosphorous imo. Good luck.

 

[Penguin59]

Will do mate, I think there were a couple of orchid fertilisers at my local shop so will definitely start there. Thanks for the tip mate!

 

[gregor_mendel]

I must respectfully disagree with soothsayer. The profile you have in that tomato fertilizer is much better than any low nitrogen high phosphorous fertilizer.

Have been useing phostrogen since the 60,s , does a fine job in soil despite being 14 10 27 NPK , i add a bit of epsom salts and use mollases , plants grow and smoke fine , a tenth of the price of canna specific wet nutes.

 

[YosemiteSam]

It kinda depends on what is in your soil. If there is still plenty of N this is not going to be good. If you lack Ca this will not help at all.

Is it native soil or a mix?

 

[Sat X RB]

there seems to be two lines of thought here in Oz on N ratio for flowering cannabis.

some people, sativa growers, say they get better results from say, orchid food which has a very low N.

others use a general rule of thumb (kush growers ... is that an indica?) that N should be below 10.

at beginning of flowering I stop supplementing with Charlie Carp and use an organic supplement that contains low qty's of N and a much higher qty of Cal.

this ORGANIC supplement is called 'backyard boost' available in Oz from Nutri-Tech. it's analysis is:

N_2.3

P_3.4

K_0.93

CALCIUM_7.80 !!!!

plus other trace elements.

this product is used alternatively thruout flowering with 'backyard bloom' which supplies extra K. (I add rock potash to my initial soil mix and by the time flowering begins this slow release K is beginning to activate so my plants end up getting quite a hit of K.)

both products are recommended for foliar spray and adding to soil.

they work very well!

Cheers ...

 

[YosemiteSam]

The Nutri Tech guys give good advice...based on achieving Albrecht ratios. I love their website

 

[Penguin59]

Thanks for all your inputs everyone!

To answer your question Yosemite, I use my own mix of organic soil.

Here are my ingredients at the following ratios:

50% Organic potting soil
30% Vermiculite
20% Sheep manure

and ½ tablespoon of dolomite lime per litre.

The next batch of soil I make will include some blood and bone with added potassium for more P & K I think. Then I should be able to get away without watering the plants with anything but pure water from seed to late flower.

Trying to get my hands on some black strap molasses at the moment actually foomar but can't seem to find any to buy online. Used some in my last grow and it worked a treat but I lost the jar when I moved house last

Penguin try coles or woolies mate in the health food section, called Blue Label Molasses in a 550g glass bottle
I've been using that one for a few years now and never had an issue with it

 

[Penguin59]

Hahaha rad avatar thanks for the hot tip b00m! Will be hitting up coles in the very near future
