Any black soil with proper pH level (5.0 - 6.5) is alright. Get some perlite too, mix it with your soil (80% soil, 20% perlite). Also make a perlite layer 1-2 cm thick at the bottom of your pot - it helps draining.

I believe this to be mycorrhizae that was moving between pots I had touching and premoistened. Any second opinions? Doesnt look like mold. Puts off no spores when disturbed. Does not have that mold smell. Anyone else ever see this?

Optimal pH for solution, when growing in 70% Promix BX, 30% perlite.
I'm having trouble finding reliable info regarding what to pH my nute solution to, I read that some like to look at it as hydro (technically soilless), and others view it as soil (due to being preloaded). So 5.5 - 6 or 6 - 6.5? HELP have done full grow using 5.5-6, peep the grow.

DWC air pump
Anyone with previous experience, what's the minimum/optimum size pump for my air bubbler? I have a cheapo single line pump, I'm assuming it's enough but not optimum. Can anyone put a number on it in cfm? Is more always better? At what point do you reach diminishing returns?

Slow growth
Hello my growmies, tell me? A substrate made up of 50% coco, do you water it more frequently than a soil mix made of earth, right? Because I find the growth of this gorilla zkittlez quite slow and I was wondering if it might be due to under-watering/under-fertilization.

False reading or Hi PH?
Is 20% humus lombrico mixed in my substrate giving a false ‘hi’ ph reading? Or is it truly over the max reading? I got one reading of 7 only at the exact second I took the picture, so I made a video. My water is high in calcium, I recently switched to distilled.

Maintaining the soil pH
I give pH'ed water, never more than 800ppm and I still always end up with lockouts. I used to not give water untill runoff but now I do. What to do after testing the runoff? It's currently at 6.0 even after a flush with 7.2. Ask many questions I need to know what I'm doing wrong.

re-using soil worth it?
Anyone with experience (give comparison growth, yield,...).... I use biobizz light mix. Normally, I only have to mix the soil with a bit of fresh soil and worm hummus to activate organic life again. And ofcourse break the old plant material with enzymes first and let it rest
