Generak Questions

Got this bad boy like 2 or 3 months ago from Costco, from what I can tell it's doing well. leaf growth has sped up expontially since putting the additional 36w bulb over it. A few questions below.

window west facing, fill soak once a week / week and a half, 36w grow bulb 12hrs a day

1. what happens if I pluck of a few damaged lower leaves?

2. some news leaves come in damaged, most come in fine.

3. does this look relatively healthy?

4. Is it wise to separate these figs?

5. general advice based on the pictures/info

THANK YOU!
