I was always told that azomite starts to really break down at the end of a normal plants life cycle. (Around 12-14 weeks and broke all the way down at six months) If you veg for longer and have a sativa that takes 11 weeks or longer it might be beneficial if you add it to the soil when first planting but it’s not going to break down in time for a top dress on a already established plant. Also, I was told that it likes higher heat (80+ degrees) to help it break down. I don’t know your grow room temp but I keep mine at 72-73.
Anyway, do you have a micro issue? I’ve never seen one in a soil grow. I use azomite in my vegetable garden for my peppers, tomatoes, and other heavy feeders, and throw some in the holes when my wife plants her flowers outside.
If you’re throwing your used soil into your garden then that’s not too bad.
