Please help me with my cycle

No, what I was getting at here is that fish exposed to nitrates on a long-term basis are more likely to develop problems. At high levels they may be killed outright. In another thread I went into this in a bit more detail, and noted that while it is a proven fact that any level of nitrate is affecting the fish, what is not yet exactly known is how this is playing out in terms of the physical damage and its relationship to the nitrate level, fish species, period of time, etc. I cited other studies in that post which delve into some of this.

Okay, planted tank and added 12 tetras. Now what?

I would wait a few days before adding the next group of fish. During this period, monitor the fish. Test the ammonia and nitrite as a precaution.
