Hey i can find npk values but i cant find what the npk values are derrived from

Eg on mega crop


It tells ya what the npk is broken down from.. I cant find this on jacks to compare individual elements.

For instance masterblend using potassium chloride instead which is not good for cannabis instead of potassium nitrates
So i want to compare deeply how close a copy megacrop is but i csnt find the 5 12 26 breakdown

That I do not know, I looked into jacks a bit, but I know nothing of mega crop. I know they are close. Maybe @rkymtnman or @TintEastwood can answer that.
Cool as spoke a bit to tint sound guy.
Ye im guesing it makes jacks superior? Or is there a fix... Like dial mega down ppm to 600 and add a mpk to 800. But that lowest everuthong els? Doesnt seem like a good fix.
Il wait for tint.

My dilema is
Megacrop 25lb £60
Jacks 322 25lb £60 + £80 postage
Current advanced £350 but i know it 6yrs and can. Grt a key n half of primeo bud under 1200.

Price doesnt bother me at all. The advanced uses some chemicals am not keen on and mc and jacks are used allover amszingly.

But if the nitrate sulphate means jacks better il pay the postage and still save a chunk
I want the best lol.

Mc does have nice chelates and aminos kelp etc
But i do brew my own bennies and kelps anyway lol.

Fun eh

I would go for the Megacrop. Use their feed sched/ratio. Mix @ the EC of your choice.
Same type of N.

It has an extra micro pinch of Silica and other amino stuff. Shameful, barely any silica.

But isnt potassium used at nitrate over sulphur also increasing N unnesseseraly? Meaning later in flower n is high whicy is why i guess i see some tip burn on a few grows?

Jacks used sulphate so sulphur which adds to oils and terpines ad they create sulphur alot to proliferate

So would jacks be superior or if i got mc how would i reduce n in flower? Swapping calnit for somthing no n profile am sure ive seen someone doing lol

Using...

Jacks Part-A
Jacks Part-B
Or
MC Part-A
MC Part-B

To reduce the N, you reduce or eliminate the Part-B.

Nute science light reading.

Nice. Dropping calnit will drop. Cal tko then. Is this why i see peeps using cal suppliments without nitrogen on these lines then?

Maybe. I assume many just use what a feed schedule tells them, or they are reacting to problems during the grow and adding calmag.

Calimagic has relatively low N for the Ca it provides. I only use it as necessary. Not using it usually causes me problems. But I'm in coco, under cmh/led/cobs, Co2...volume cranked up.
Sometimes Mg may be needed if ratios matter.

Not saying this is gospel, just a graphic I found on the interwebs.

Has enough sleeping peeps to give me 3000ppm co2 in 2hrs sleep open window drops to 1200.. So i suck that up and blow fresh o2 in the bedrooms haha

And 2
Urdwc to change to coco after this cause am lazy. Under 1200watt 3030 epispar top bin led.

Need shroombags or sumin co2 here 1 person house can see the difference in co2.

So no so different lol.

Ive grown for 16 years designed urdwc systems 8yrs ago n got the design stolen haha.
I wrote studies on fluming and airstones ya can find on a few sites here.
And been using advanced nutes for 6yrs now.
A n b b52 bigbud bud candy nirvana overdrive.
Brewed teas years alfalfa for trianacol pgr n always kelps. And a number of fungis and bacteria. .
Use spinosads if i get infestation thats if the neem and lavendar doenst work. And the rapeseed oil 1% fails.
No BUgs too small al fk em all haha.
I grow masterblend tomatoes nft wall. And aquaponic veg on my pond lol


I normaly grow trees record was jackhere 14week from seed 27 oz. Yeah im from the heath robinson days we all had to try it lol.

I get 0.9gpw hps and 1.8gpw led
Just worried as i swap mega crop il brew teas but am dropping somany boosts its scaring me my head says u aint gona yield like u have been dont do it..but the peeps all talk n pics all walk miles i wana trust the salts and say no to hydro scams. But the claims seem so damn good on my boosters its hard so am doin side by side leftovet advanced and new megacrop.. All same strains 4 each side dtw coco 1 600 over each 4.

So i just wana makesure i get the max outa it being as my advanced will be full lineup it wudnt be fair if i didnt usr boosters that the plants want.

Ill read em as i go but i hope a rought guide to follow lol.


Not braggin im jus a small fish lol. But am defo not new on the scene. Just freaking out as im trying to debunk the past 6 yrs of faith and consistant yields lol


What dya think to
Biobizz calmag 100% natural ingredients and a “friendly”, nitrogen-free formula.
