Till now. So she is starting to eat from here oldest leaves.
Looking for Nutrition to survive.
It's normal for them to get yellow and fall off at some time.
Your bottom leaves turning yellow because you lady is showing you she's hungry.
It looks you Are looking for a small compact plant with what I see it is in a small pod.
Suggestion-
Feed as soon as possible
Add 1/4 dose grow nutrition from recommend suppliers maximum in 1 l off water. It's an auto and they eat less.
And start feeding her my friend.
Get the lights closer with 10cm so she gets going.
