Of course adding a lot of fish at one time, or big pooping fish, can cause problems from insufficient bacteria being available. And, growing plants consume a lot of ammonia just by growing, so that reduces the immediate need for ammonia eating bacteria.
All good points and I agree. I said usually 1-2 months but there are many factors the OP didn't tell us so I was more making a blanket statement.
