Instead of making many separate threads on this topic, I would suggest you first do a bit of research, or at least stick to one thread. Check out my journal that I have previously linked to you, Cheetos thread I linked you, as well as others who have posted their Atta journals here.
In general, it is not wise to use soil. From what you have previously mentioned, it also sounds like you have been over-watering by a lot. However, since you have successfully kept the fungus alive for a month, the care can't be that bad. For long term success though I suggest you read those threads that I previously sent you, as they cover the proper care for Atta
Because of this the moisture needs to be as close to 100%
This is common "folk wisdom" for Atta care, but in my experience true 100% humidity is detrimental for fungus. This typically means some standing water from condensation which typically melts away the fungus. As long as the fungus is in a typical plaster setup and watered every now and again, that should suffice
