@Wikcsi. Welcome to ILGM.
Being in the window will make the plant leggy.
The glass has uv inhibitors that will limit the useable spectrum that the plant receives.
A bit of lower leaf die off is normal as the plant grows and shades out the bottom.
Also that plant is getting a bit large for that pot.
Here is a support ticket to fill out.
It will give us enough info to make an informed diagnosis.
