She was now definitely flowering! I started to recognize the smell - very faintly, though. That would change in the next week, but for now I was delighted how fast she was growing. The flowers were now easily spottable and her stem was getting even thicker. The whole plant started to become bushier.
I still was cautious with the nutrients and decided to err on the lower end of the spectrum as this grow is not about optimizing results, but to get a feeling for the process.
