Ok, so today something weird happened to my auto blueberry after transplanting it from the party (dixie) cup into a ocean forest/perlite/light warrior mix. Is it flowering? It's so small though.... Will it grow more?

It's only 5 cm across and I'm pretty sure those look like mini-trichomes.

Lesson to learn from this is that autos need something light like light warrior to start but they don't like being root-bound so a bigger container is necessary to start from. However the problem with that would be over/under watering as they are easily flooded due to being seedlings and easily under-watered due to their roots not reaching very far down.

Any suggestions on how to manage feeding it for its whole like in light warrior? How big should its container be?
