Amino Acids, and reduced THC?

[420hobbygrower]

So I just purchased some Impello Bio Lumina - an amino acid product. I then found a research article that claimed adding amino acids significantly reduced THC - that's the biggest question for me here. The article is linked below.

Just wondering if anyone here has any experience or knowledge of this. I'm thinking about returning or not using the Lumina now. I also have used Mr Fulvic in the past, and I believe Bill Farthing mentioned at one point that too much Mr Fulvic, or use late in flower could reduce THC. Mr Fulvic has some amino acids in it so now I'm wondering if that's why.

Secondary note - the article also mentions the amino acids reduced calcium and iron, and increased nitrogen and sulpher. I'm doing DTW using Jacks 0-12-26 and PureCal (cal nit), and calcium being a big talking point these days, a reduction in calcium (and increase in nitrogen) wouldn't be ideal.

Anyone have any thoughts?

Does anyone here use amino acids? Seems a lot of people do, so maybe I'm worrying about nothing.

A buddy of mine told me that amino acids are great in that they reduce stress on a plant growing, but therefore diminished potency is something to worry about as stress is what drives plants responses.
I really don’t know but your post reminded me of that!

That's something I was thinking about, thanks for the reply!

I'm using amino acids (big bud powder/liquid) for a very long time and the buds i produce compare positively against "99%" of the stuff i see around.
That's including potency, smell/flavour and bag appeal.

"Medical cannabis plants in the drain-to-waste cycle matured 4 weeks earlier, but at the expense of a 196% lower maximum tetrahydrocannabinolic acid yield from flowers and a significantly lower concentration of monoterpene compounds than in the recirculation cycle. The amino acid treatments reduced the cannabinolic acid content in flowers by 44% compared to control in both nutritional cycles and increased the monoterpene content (limonene) up to 81% in the recirculation cycle and up to 123% in the drain-to-waste cycle; β-myrcene content was increased up to 139% in the recirculation cycle and up to 167% in the drain-to-waste cycle. Our results suggest that amino acid biostimulant supplements may help standardize the content of secondary metabolites in medical cannabis. Further experiments are needed to identify the optimal nutrient dosage and method of administration for various cannabis chemotypes grown in different media."

"196% lower maximum tetrahydrocannabinolic acid yield from flowers and a significantly lower concentration of monoterpene compounds than in the recirculation cycle"
Interesting but those huge numbers seems strange. they should be using common available amino acid products, because those amino concentrations used i have no idea if is comparable with what we are using.

"The amino acid treatments reduced the cannabinolic acid content in flowers by 44% compared to control in both nutritional cycles"
Again strangely huge numbers

"and increased the monoterpene content (limonene) up to 81% in the recirculation cycle and up to 123% in the drain-to-waste cycle; β-myrcene content was increased up to 139% in the recirculation cycle and up to 167% in the drain-to-waste cycle"
Again seems odd to me that only adding amino-acids would make such a huge improvement in terpenes, and why would terpenes levels change so dramatically between DTW and Recirc. systems?

"Medical cannabis plants in the drain-to-waste cycle matured 4 weeks earlier"
What???? .... this is fishy.

i have many questions raised on this study, also some concerns.
The study should include at least 5 different trays with different concentrations of aminos for 1 control tray without the aminos, and imho all with the Same Cultivar Clones, irrigation, Media and etc, everything being EQUAL only changing the aminos concentration on the treated trays.

In this case study they used only one AA concentration and only two different trays.,

Also its important to point out that they are using EC 300-400uS of AA on top of base nutrients, witch is much more than we are using for sure.

Thank you for the detailed reply!!

Overall informative, but like trash a said: strange high numbers..what if your using Mr vulvic just through the veggy phase and stop when the plant starts to flower?
Less stress in the veg and no loss of thc through flowering. Never used mrvulvic.
Sounds good and can be correct?

This study is a fail imho, i lived with Agronomists for a whole year, also worked in a orchids micropropagation lab that same year.
All studies people did in the university included at least 5 treated trays for 1 control tray and many used 10 different treatments trays for 2 control trays, to get real useful and real data to work with.

I helped some with their experiments/studies at the time, leaf surface area measurements, leaf nutrients contents, soil salinity and nutrients content, BRIX levels etc etc etc all were carefully collected/measured/tested during and/or after.

I use amino acids untill late flower. I have for many many years . I currently use Raws powder amino acids 1/8 table spoon per like 12 gallons. Here's a pic of my gg4 week 8 starts tomorrow.

 

[Redneckx]

Still not quite sure about using them, how big is the risk of loosing potency? also want best results for my grow in taste/smell..

 

[7munkee]

I use fulvic during veg but quit at flower. I will use it at flower if I have to top dress, but I prefer to top dress a week before flipping, if at all.

I ALWAYS see a dramatic improvement as far as turgor after suing fulvic.

Well this is interesting! I’m a first time grower and all the nutes I’m using are chalk full of amino and fulvic acids.
