Why do we use pot fertilizer?

[The Celt]

Yes that is the Mega Crop, price is similar to here ($120 CND) and simple as can be which I like

I hear you loud and clear. I live in California too, and the price of power has gone through the roof. I'm paying more than double what I was just since 6 years ago. And since the chapter 11 was approved for PG&E, I heard the price of power will go up at least 5% a year. I guess we have to pay for all of their lawsuits and still give the investors their profit for the next five years. You would think the cost of the power would come down after that, but I doubt it.

So, needless to say, I do most of my growing outdoors now. Indoor growing is a thing of the past now. I still use one of my tents. But it's just to get my outdoor crop an early start before going outdoors.

Same here. Early start for the year. I have a 150w HPS i run in the winter months

@MrSauga (I think) recently posted a dry weight NPK breakdown of plants at various stages, so long as it is there in the medium, in enough quantity, the plant will use it as it needs it.

I believe that was Shed with this chart:

Thanks @MrSauga , you 2 are 2 of the few who actually use science and is one of the reasons I enjoy your guys journals

[LosSerpent]

Btw, this was the stuff I was talking about

 

[LosSerpent]

Exactly. The cost of using nutrients like Advanced Nutrients is the price I would pay every time I left the hydro store. It would cost at least a few hundred buck for a complete grow. I think the Jacks is about 40 bucks a grow.

But I'll tell you one thing that is not a good nutrient. It's smoke, and I am a little worried about my summer grow. They are only taking about half the water is usually feed them. So i'm thinking there is some negative effect that the smoke is having. It's been around for a month now.

Can you post the chart for Jack's classic?

Can you take a pic at the chart I posted, it looks like it has everything weed needs right? Maybe too much N, but still

Hey @LosSerpent , that actually looks like a decent fertilizer but will need some extras. I don’t see any calcium there at all, and there are some missing micros.

If you use that at 1g/L, some Cal/Mag at the recommended dose, and get some liquid kelp you should have a decent feed. Also, if you can source some diatomaceous earth, sprinkle some on the surface , as you water, it’ll add calcium and silicon to the medium that will improve the health of the plant.

 

[MrSauga]

The nitrogen should be mainly in the nitrate form as it provides more compact and controlled growth. More extensive leaf and stem growth occurs with ammoniacal and urea nitrogen. In general, to avoid excessive stretching and oversized leaves, more than 60 percent of the nitrogen provided to plants should be in the nitrate form. Ideally 70 to 80 percent as this will provide a moderate growth response and avoid overly large cannabis plants.

I'd just like to add what @The Celt mentioned.
The nitrogen content is mainly ammoniacal based and nitrogen should be mainly in the nitrate form as it provides more compact and controlled growth.

I'm not sure why so much Sulfur trioxide (SO3). I don't see any Ca content there either. Honestly I don't know if it will work well with cannabis or not so be careful on the initial application with a low dose.

Thanks for the answer. Any idea what the numbers in the (+2) mean? I have. A similar fertilizer without those numbers

Thank you. Imma just use it for hermie seeds as a side grow just for seeing how it goes... Also I have this, it has other nitrogen "stuff" no idea what it is. I'm really out of my field here.

 

[The Celt]

@LosSerpent , those refer to the addition of Mg0 (2%) and S03 (22.5%)

and @MrSauga , I am thinking it’s a tree fertilizer, I don’t speak/read Italian, but there is enough similarity to French and Spanish for me to recognize a few of the listed names...I see olive, apple (I think), kiwi and another that might be either cherry or plum. They are down the right side of the bag. That might be the reason for the extra sulphur.

Yep, it's for all fruit trees and bushes


I'll try to use this for my side grow until. I can get my hands on mc, which is currently unavailable

This is the way Cali does politics.
Socialists passed their version of the New Green Deal ... this is what we get.
State required PG&E to research and invest in 'alternative energy sources' so they didn't repair and replace old equipment and it started fires.

Now ... the transmission lines can't carry enough juice for demand.
JUST like Venezuela.

And, energy is just part of Cali's problems.
They gonna triple property taxes, increase income taxes, sales taxes, etc.
We paying 50 cents a gallon state tax on our gasoline ... and it will go higher.

It now costs upwards of $400 to register a car for one year ... that will at least double.




I never thought I'd live in a third world country ...

You read my mind, i was going to ask if someone could explain the different types growths from different forms of nitrogen. Harley Smith speaks about that in his videos, but I have a hard time grasping it.

He says something about how it takes alot of plant energy to process one of the forms of nitrogen.

 

[MrSauga]

Well it could be he is referring to the urea. Urea has to be broken down into a useable form which would be ammoniacal. I did a little write up on it here if you wanted a bit more info.

MrS your ladies look perfect man. Your knowledge and attention to detail shows in your girls dude. :headbanger: :Namaste: Thank you! Hope ya don’t mind me asking a quick question about the nitrogen discussion. I’ve been reading into urea nitrogen and how once it’s broke down it has a neutral...

[bluter]

wow this went a bit sideways lol

I guess I should still check for ph, since terra professional calls from 5.8 to 6.2ph.which is lower than normal soil?

you are not in soil. i dunno if that terra media is balanced (dolomite ) - so i would ph

this is a standard ph chart ..

ph chart

the "soil" the chart refers to is a neutral media - like the product you currently grow in. it does not refer to outdoor ground soil or LOS type soil.

you can safely ph down to 6.3 - 6.2.

Can you post the chart for Jack's classic?

skip it for the price. essentially the same as the two part mc for a lot more $$ $$
if you can't grow with mc - - you can't grow ...

italian tree nutes eh ? ,... try em anyway lol

OK thanks, any idea if mc has everything weed needs in it? Or do I need to add Cal mag or some other stuff?

 

[The Celt]

The only thing I have used aside from the MC is diatomaceous earth that I spread on top when I first put them in the pots, adds silica to the mix
