Mineral nutrients: is it necesary to mantain an active microbiology?

Hey there. I've just started a new grow and am using a mineral nutrient line this time (Advanced Nutrients tri grow combo).

Because the nutrients I'm giving my plants are already available for the plant to absorb, I've been thinking if it's still necesary to use microbiology suplements and/or mantain an active microbiology in my soil, as no nutrients need to be degraded for plant uptake anymore (as oposed to using organic fertilizers).

I'm talking about mycorhize, good bacteria and fungus. Are they still beneficial to the plant when using mineral nutrients?

Maybe the nutrients present in my substrate are still worth being processed by these despiste the fact I'm feeding mineral nutrients?
If I were to use molasses some time during the grow, would it be smart to have active microbiology then?

Interested in reading what you think about this.

If you are feeding non-organic nutrients. I think that will kill the life in your soil.

I think there's a bit of misunderstanding around the subject, i feed mineral salts to coco multiple times a day, if i look at a sample of run off under a compound microscope its heaving with life forms.

This isn't my thing, the grower knows less than average he feeds his pots twice a week with mineral salts.

In recent years farmers have been sterilizing soil in the fields around my area with steam and they sure as know what they're doing.

Long story short the tomato grower knows some expert in horticulture he told him to feed every time he watered, when I say expert what i mean is he owns acres of greenhouses and makes a living from horticulture.

I’m no expert, but from my experience, I feed mineral salts in RO water 3x daily in flower, I’ve done it with and without any organics, and by far the better product is with some organics mixed in, in my room. Mychorrizae works. In organics it might work a little harder, but it works in my synthetic grows, visibly. I use liquid kelp, for micronutrients etc. I use fulvic acid, fulvic acid chelates assisting in nutrient uptake even more. And lastly I use a quillaja/yucca wetting agent.
You don’t have to use what I use just saying that to say this, I don’t think one side has ‘the way’ I think finding the balance in the best of both worlds is the way.

off the top of my head, nuclear waste, gamma rays and hydrochloric acid will kill microbes too. can i add those to your list???? lmao

Human poo will make them grow as well! Need me to send you some nutes?

Makes sense. Do you use any bacteria suplements too or just fungus?

No bacterial supplements as of yet, I am cautious of introducing beneficial bacteria because without all the organic checks and balances I feel like it could lead to problems. But I haven’t been extremely thorough in my research there, I just read some Jeff Lowenfels books and it seemed like both good and bad bacteria thrive in a grow, but with organics there is the microbiology to keep it in balance, in coco or hydro that is less able if at all. Mychorrizae is more of a symbiote imo.

I push people to go outside the purely cannabis community/industry for better understanding of nutrient uptake and availability. This is nothing new all of this has been being perfected since the 1800’s for agriculture, people over the last 60 years or so have applied some of it to cannabis, but the majority of the knowledge iceberg is in crop & soil science and horticultural/botanical texts.

If using soil you should be fine with both. With coco you’d probably be fine. With rockwool I would use any organic amendments. The reason is that if you have a medium with its own buffering capabilities you shouldn’t have problems, but if the medium is inert then anything living in there can cause ph fluctuations that can cause problems

we use both bacteria and fungi whilst running 3.0ec seemingly with negligible effects on microbiology
regarding rockwool/hugo blocks we have found adding biostimulants/microbial products helps increase flavour/terp profile, also increases resistance to stress/pest pressure.

Which bacteria and fungi products are you using?

i,ve since bought a digital thingy for my microscope, I'm not sure if i can upload the video but a gify will give you a small insight to the life in coco + ab

5 ppm of chlorine added to my nutrient and fed 2-3 times a day.
