Dialing In MEGA CROP for Auto's

[pop22]

Good info. I haven't tried the 2 part, but I have no real desire to. I don't fuss with feeding charts etc, I think they are total nonsense. I start feeding at 10 days and I feed at full strength, 500-550 ppms. I've seen no detriment to the plants in doing so, but no real advantage to it either ( with soil ). If I am transplanting to auto pots, or a larger pot I feed the same day, I want them roots to spread out and gather food. I don't buy into the idea of making them hunt for it or water, roots spread through the medium faster when there is abundant food and adequate water for them.

I start at 150 ppm first week and work my way up. I go to about 600 to 640 ppm in flower with just 2 part MC and nothing else added. 2.5 grams part a. 1.5 grams part b per gallon for all of flower after the stretch and no problems here. Every strain has done well like this for me in flower. Anything less of part B and I got a calcium deficiency. I found my sweet spot.

I would love to try the 1 part but I'm scared too. Lol the 2 part is working so well for me and I have heard of some ppl having trouble dialing in MC. That's why I tried the 2 part instead of the 1 part. Thay and I was used of gh flora trio plus calmag and armor si and some of there other additives I ran also. I had quite a few bottles and it was time consuming. I like to keep it simple. And mega crop has been that for me so far in soil and in coco now. I bought some coco coir nutes from AN sensi coco grow and bloom in case I have problems with mega crop in coco. But so far they're loving it. I'm soil I feed after 10 days if its fresh soil or if reusing soil I feed 150 ppm starting off and same in coco I start feeding 150 ppm from time I plant the seed to week 2 then I up my feed and ppms. I used to follow a schedule but now I'm to the point I just look at the plants and know how much to make up for them. Lol. I know my max to not go over and I keep it at that. How many grams per gallon of the 1 part does it take to get to your target flower ppm?

If it works for you, then your good! If it ain't broke, don't fix it!

After many grows with MC, I’m still having issues and have a hard time to get a healthy plant from start to finish. In my current grow things were really doing well for the first 4-5 weeks, here they are at Day 30

I can usually get to this stage no problem but Soon after this is when things tend to turn from me.
Here they are at day 56

But still, growth was good but I think the flower will suffer due to the troubles from transition on. Middle plant has faired the best and may still finish strong.

I’m at Day 52 and was starting to see some similar light yellowing on the leaves of a couple plants - my 3BOG and 50 Shades of Grape, specifically. I’m in soil/perlite and autopots and running MC at 550-560ish/6.4 pH. Last night, I turned off the reservoir and when the pots dried, bottom fed with Recharge. Huge improvement this morning. Lots of new growth and most of the yellow is green again. Food for thought, for a possible easy fix.

Is mega crop Agricultural grade or pharmaceutical grade? And is there really a difference?

I do not think USP is a thing in fertilizer? Non of them are for human consumption.

If you consider that MC is made for agriculture and has been strictly formulated and labeled to meet various agricultural regulatory agency requirements, yes it's definitely "agricultural grade."

There are big difference in grades in terms of uses - pharma grade is meant for human input, often even injection, with high(est) purity and often sterilty required; the other grade is for farm plants and animals.

MC is not pharmaceutical grade. Meeting pharma standards would make the cost ridiculous. For example, cell culture media (generally prepared from powdered nutrient mix, much like MC) often costs >$15/L, with this after it's diluted! $15 will make a massive amount of diluted MC. Otherwise, there are no pharmaceutical standards for many of the ingredients (and pharmaceutical grade sourcing is not needed for most, if any); MC is not manufactured under aseptic conditions (made in a high-grade cleanroom); lacks pharma-required level of testing and documentation; etc.

I
don't think there is such a distinction.

Here is a quote from Greenleaf's FAQ

MEGA CROP and our fertilizer products are Vegan fertilizers, and Organic compatible but do not official Organic (OMRI) certification. Vegan fertilizers have the exact same standards as Organic fertilizers as far as toxins, heavy metals, and other contaminants and pollutants. Our products are compatible with organic growing methods because they benefit the soil conditions and living microbes, do not contain any pesticides and do not harm soil or ecosystems.

“Organic” fertilizers refers to a certification done by the private company OMRI, which will give OMRI Listed® certification once paid the appropriate fees ($$) and requirements are met.

Vegan fertilizers have several advantages over Organic fertilizers.

• Not sourced from animals, so no risk of antibiotics, antiobiotic resistant bacteria, pharmaceuticals, hormones or pathogens that are associated with animal based fertilizers
• Far more water soluble and available to the plants, for better absorption, quicker and complete uptake by the plants
• Lower environmental impact
• Not supporting the animal agriculture industry which involved cruelty.

Also triple tested for heavy metals

Yes, our products have extremely high quality testing standards and exceed standards for growing plants fit for human consumption. MEGA CROP is tested a minimum of 3 times for heavy metal screening.

1. Before sourcing the individual ingredients that make up the product
2. In house testing after completion of final batch
3. External 3rd party independent testing of final batch

Testing for Arsenic, Cadmium, Cobalt, Copper, Molybdenum, Nickel, Lead, Selenium, Mercury and more are standard. Products exceed organic level certification requirements.

now I’m real confused cuz I’ve always heard salts would kill the micro organisms not benefit them. wouldn’t mega crop be considered a “salt”

 

[BII]

What's wrong with salts? Essentially all the mostly rather simple nutrients involved here are salts (nitrates, phosphates, carbonates, amino acid chelates; etc.), otherwise the substances wouldn't be soluble. Essentially these same soluble salts/nutrients are in healthy living soil, with fertilizers just supplementing or copying what's in healthy soils. Many of the 'salts' in plant nutrients are also good culture media/nutrients for microbes. Unless soil/media 'salts' levels are too high (likely more affecting the plants first), there should be no killing-off of soil/media microbes.

 

[pop22]

I've had red wigglers living in pots I fed MC to. No. that's a line of bullshit perpetuated by the organic purists. And BTW, there is absolutely no difference between organic and mineral based nutrients in the soil. They are all the same to a plant. The few micro nutrients that need to be chelated for MC are done so using amino acids, which is what soil bacteria do to them and creates the same ionic form that the planst need.

Now ask about those "nasty chemicals" in manufactured nutrients. There are none.... NONE! I've asked every person who has ever said that to me to tell me the exact chemicals they are talking about, I've even emailed so called experts and asked, NO ONE ever has any kind of answer, because they are all just spouting heresay! Abut the worst thing might be EDTA, although even that is debatable as it's considered a food grade compound and it used as a preserative!
