SOIL Mycorrhizal Preferred Brands

[dmpmfd]

Just wondering if anyone has a preferred Mycorrhizal brand they prefer over others. GTS results in too many links to try to figure out which one is better for our girls. Currently running in last of the premade scammer soil bag (lush.garden which has folded but which used Fox Farms product line) with the FF Trio nutrients (Big Bloom, Grow Big, and Tiger Bloom), Starting next grow with Bud Trainer BudCups with NLS original concentrate in 5 G fabric pots with Coco-Loco as per GWE's post of Review of Nature's Living Soil for Growing Cannabis | Grow Weed Easy​. Hoping to increase my root ball size larger than starting from seed in a 5G pot since all my plants have only grown out aa root ball about half the size of the full pot width. Hoping to be able to reuse the soil mixture over with amendments as needed to recycle the soil & lower costs instead of buying new Coco-Loco bags each grow. Organic brands preferred since looking to get away from liquid fertilizers.

I don't have much experience with Mycorrhizal brands, but when I grew in living soil I also had the thing where the roots didn't fill the whole pot. They only got like 3/4 of the way down. You can see a clear line where the soil is darker. That part wasn't fully colonized.

I figured it was because I wasn't giving enough water to get the soil wet all the way to the bottom. After harvest, the bottom soil seemed it might have been too dry for full root colonization (or for Mycorrhizae to survive), but I'm not sure. It could have been something else.

I used NLS with Coco Loco. I think it already has Mycorrhizae, so I didn't add extra.

Looking back, those plants were good but got deficient by harvest day. I'm not sure the exact issue. I had assumed I should have given them more nutrients in the flowering stage, or maybe more nutrients would have been available if I had tried to ensure water always reached to the bottom. Like maybe some nutrients was "locked up" in the bottom soil because it was too dry.

PH was probably also a factor. I was using citric crystals to get the pH to 6-7 (my tap water is 8+ pH), and I think it started building up in the soil over the course of the grow, since I wasn't giving enough water to get runoff (I didn't want to wash away nutrients). But the one time I did get runoff, it came out really low. So I started using spring water after that until harvest, so I didn't have to use the citric crystals any more.

But the plants just seemed so pale all over that I think they needed more nutrients overall, not just the incorrect pH (though I bet pH is what caused all the brown spots)

Curious if you have any thoughts on that.
