I repotted her to her final pot this week (16 liter pot). I first wanted to go for a 12 liter pot and change to a 16 liter pot after some more weeks but I don't want to wait forever to harvest her, so I changed my mind.
I topped her once more today and will do it at least one more time, maybe even twice. We'll see in the next few weeks. But I plan to start the flowering stage by mid-October at the latest.
Will continue to give her Piranha until next week.
