You will see the beginning of bananas.. you will see bright yellow spots sticking out from the buds.
If you see those, and i mean spend a good 10 or 15 min per plant looking...then come back for more discussion. If not, keep an eye out every few days...you may be OK, maybe not, but whatever happens dont freak. Let it be and move forward.
