Mega Crop vs Dyna-Gro comparison grow

[swedsteven]

Sorry to ask .....

How many oz dry .

Sorry to ask again.

 

[lukio]

Where is my calcium deficiency?

well...like i said, i think this is the start.

....lol

how exactly do you think those older leaves all-of-a-sudden developed a 'calcium deficiency' late in flower?

if i had the answers i wouldnt be askin. Why do my symptoms match Cal def as stated on canna sites??

Do you think the nutritional needs of these plants increase near harvest? They don't.

i know.

If I were you, I'd quit feeding so high. 1.0 EC in containers

i should of been more accurate. i currently feed once a day between 0.8 and 1ec. im growing like 15 strains so it varies. PLUS i never had issues with V1 at those EC numbers...and i probs grew 100 plants with it...i still have a load so i might try the old lot again.

Anyhoo, i thought you might have the answers but it doesnt look like it. cheers anyway. cheers for the grow

Depends on the silica potency. DG Pro-tekt is about10ppm per ML. GH Armor Si around 26. Products vary greatly.
Based on the analysis breakdown, the total N PPM seems high, relative to the other primary elements.
Does DTW coco/plants make use of the ammoniacal, or is it just leaving with runoff?

Been using Agsil16H for years, 560g to 1gal H2O.
2ml-ish/gal of H2O every feed and every stage, even use it as a pH up when I whoopsy the amount of "prep and etch" pH down.

Works out to about 50-100ppm in the mix and never had an issue, only strong solid stems that take whatever I give when super cropped.

Started out with DG Protekt but too expensive for watered down potassium silicate. Tried all the varieties of mono/silicic acid as well, ie OSA28, silicium, aptus fasilitor.

Yes, that's what a rep told me.

that may technically be true, that the founder has only grown cannabis once, I can’t say it isn’t without doubt but Dyna-Gro has been around for decades, and is definitely knowledgeable about cannabis. He’s done a few interviews, including one with the DGC that I really enjoyed.

i always view feeding charts as maximum values at best or a waste of ink more often.

I asked for EC, you gave me ppm. What scale is your TDS meter on? Actually, don't worry about it. Look, feeding with Grow and ONLY grow from start to finish at their recommended maintenance dose will crush it (I think that's 1/2 tsp/gal). No offense but you need to make this as easy as possible. Don't worry about pH. Don't worry about all that other shit you were feeding with before. Ignore feeding schedules, forever. Learn to feed based on EC and more importantly, learn the basics of plant nutrition from non-canna websites.

Btw, overdoses of silica results in rigid, brittle leaves.

Did you miss my previous comment??? Once you understand that feeding schedules exist more to move product than any other reason, you can stop taking them so literally.

I do feed based mostly on EC/PPM usibg chart as a refference. Once you know your product then you know what that ppm/ec equates to to your plants.
Ex: my 1200 ppm of TechNaFlora may be equal to your 800 ppm of DynaGro according to the plants. So going by someone's EC that's using different nutes isn't always that helpful.
But i get your drift n had i had more time & patience i may have done fine.
After reading the chart i was just so baffled by the buffoonery that it equaled out to be in my rez.
Maybe using the Pro-Tech as is specified with lowered doses incorporated.
Good point @TintEastwood .

Aptus Facilitator is the shit. Not your basic silica.

Aptus Facilitator is the shit. Not your basic silica.

Silicic Acid

Aptus does seem to be the only company selling this retail in the US. agro-solutions has the same thing as facilitor, execpt it has a little copper and zinc added. They have a California office, but they only deal with commercial ag. Wouldnt even give me a distributors name. lol. Here...

www.thcfarmer.com

Actually it is, **basic silica** potassium silicate with a polyethanlene glycol stabilizer or the like.

Also forgot where I read it, likely from an actual soil science/ agronomy article, that many of the silicic acids marketed to "growers" have added trace elements like arsenic, zinc, and manganese in order to trigger a SAR response in the plant to boost it's immune system.

EC is universal, your 1.0 EC is everyone else's 1.0 EC, though the formulas to get to 1.0 EC will vary.

PPM is in .5 or .7 conversion based on the origin of manufacture of your nutrients or TDS probe.

This is why we focus on EC and not PPM as PPM is subjective.

Thnx but, uh du. We know.
Hey @lukio
What's going on man?
Switching nutes, different lightning determining factors, ect...?
Thought you were the Rasta Grow God bro.?

 

[OneHitDone]

cheers, but i disagree and they were nicer without it a couple grows before. one plant gave me the typical rust spots...

im in coco, feeding 1ec in flower with RO water, which by the way, i HAVE to add mag to if i dont want a deficiency. everything fine until late flower.

im all ears.

ive gone back to Canna Coco A+B and have a tonne of plants at week 3...my fingers are crossed it doesnt happen again.

Are the rust spots you are talking about like the plant on the right in this pic?

 

[lukio]

@OneHitDone you're still on my ignore list, which doesn't seem to work?! but seems as youre currently not being an ignorant shill for a scam led company, i'll answer your question. Yes, one of them was heading that way.

@hybridway2 same as above except i removed you from my ignore list in the hope that you'd actually talk food profiles/ppm' instead of blaming your lights...i see youre kinda gettin there....congrats, thats progress.

....lol

A true 'deficiency' would've shown up after a week of using Mega Crop on NEW growth, not 9 weeks later on a leaf that's 5 weeks old. How do you not understand that??? Did you read that link that I posted?

Again, DynaGro supplies 2% calcium which is 1/3 of what MC supplies, where is my 'calcium deficiency' on those plants?

if i had the answers i wouldnt be askin. Why do my symptoms match Cal def as stated on canna sites??

Because canna sites are literally the worst place for horticultural knowledge. No offense but they're usually filled with a bunch of amateurs thinking every problem in their garden is either related to cal/mag or pH. It's laughable actually. Or in your case, thinking you have an issue when things look pretty damn good. Lower your feeding levels and call it a day.

Having either of us on an ignore list do to your own hypocrisy issues is just whack.
Nobody pushed those shitty lights dude. Let that go.
I do wanna talk food. But i dont not wanna be told I'm full of shit when I'm clearly not.
Your plant pic appears to be nute burn before cal defficency. But hey. What do i know.

lol okay then, i didnt have a deficiency. im seeing shit, those plants were healthy af.

yeah i read it.

im not talking about the newbs.

good day, sir.

One thing is for sure, you have no idea what you're seeing. Just last month you thought it was a potassium deficiency : https://www.rollitup.org/t/lights-camera-procrastination.997504/page-2

I'd love to know how it's possible that you're deficient in potassium with the mammoth amounts already supplied by MegaCrop? Have you ruled out an iron deficiency? What about a manganese deficiency? lol

What you're likely seeing is operator error in the form of overfeeding. If you don't think daily doses of 0.8 - 1.0 EC is a lot of food then you're insane.

lol! it does look like potassium def though.



i was asking people in my diary what they thought, whats wrong with that? seems a good place to ask.

I've grown in coco for 6 years at those numbers without ANY problems ever. You'll notice breeders like Vader on Youtube also feed those EC ranges.

When i lower my EC i get pale plants. MC change their cal and i get issues...

Why dont you try growing under led in coco before spouting bollocks. i knew you didnt know when ya dropped the snarky calmag "joke" instead of offering advice.

Carry on ignoring the issues you documented though...

You take it easy now, bruh

He's in Denial is all. Remember he said "different lighting" when given a potential solution? That different lighting requires different feed then an HPS/MH/T-5 Grower. He's right there but he'll deny its a problem for oh say, 70% of led growers. Instead, its Grower Error. Which it is only because the answers are mostly Bro-Science that rarely equates to much help. It is hatd for many of those using plain white led in CoCo & sometimes other lightly air-rated media.
I call it "LedDefficiency" until there's some better understanding on the topic.
At first Lukio had x1 answer & x1 answer only = Jacks 3-2-1.
Guess that's out the window for now.
Back to big money Canna A+B hu?

Yep, you're right. It's your super special combination of lights, media, and food, that makes you and your garden a special little snowflake. And your plants are so special that even when given bountiful amounts of the essential elements, they still somehow show deficiencies.

@lukio your answer lies in one or all 3 of the elements homebrewer has listed here and the ratio's of each and how they interplay with each other in solution as far as chemistry.
I have a strong hunch exactly what the issue is but will bite my tongue in case your one of those "All Nutrients are the Same" type of guys
