*Old Thread Bump Alert* I sprinkled this stuff on some clone roots when planting them into dixie cups. A few days later I'm seeing some leaf curling, which indicates too much nitrogen. Manna Mix is not a very hot soil, and I used a weak solution when watering. So I would say the Azos does what it says, maybe too well for a sensitive LA Master Kush hybrid.I wish to buy into their products as well but I am worried about the plants getting too much nitrogen between whats in the soil that the mykos makes it easier to get, what the Azos pulls out of the air, and any N in applied nutes. What do you feel the chances are that one could overload their marijuana plants with nitrogen and calcium (from the Calcarb)? How often do you think one should apply Calcarb?
