Cotton plants are maturing

After about 4 months after sprouting the cotton plants, They are approximately 30 cm in height and I moved them outside to enjoy a bit more sunshine. Afterwards the stems of the plant turned a bit reddish and became more sturdy, probably to adjust to their lives outside. There are some buds forming in axils of the plant, but I am not sure id they are leaf buds or flower buds. I am hoping that they are flower buds, because it would mean that cotton will start forming after the flower has matured. 🌱
