Thanks!

It looks quite healthy but the transition from hydro to not-hydro (geoponics, i guess?) will trigger a lot of physiological changes and internal reshuffling of nutrients. It’s inevitable.

If you click on the post I linked, you see that the plant barely had any roots left, because they were completely mush when I bought it.

The substrate you meant is called “LECA” (expanded clay balls), which wick up the hydroponic nutrient solution. It’s just another form of passive hydroponics :)
