This plant looks very healthy! Please reduce the nutrition a bit, and give her more light! You can lower the light to 30 cm.
Even LED-Light from the side would be good. Only the leafs need the light.
Half a litre of water, per day, is enough! It does not need to be soaking wet. Overwatering is as bad as underwatering!
@FraFra__frankenstoner_Dont_panic_its_organic, thanks! Despite the lag in development, she looks good. I appreciate your feedback. I have lowered the light to 40 cm and will lower it further. She is in a relatively big pot, so I need 2-3 L per watering to moisten it well. And then I wait for the soil to dry and the pot to get light before the next watering. I'm also using the finger method 😆
