What is wrong with this arch?

Saw a tropical Lilly tonight on my way in.
Good to see. I now know we have tropical and hardy Lillie's. 🙂

I went down to look at the gauge as soon as i arrived home. I panicked when I looked at the gauge as it had dropped 20 lbs. I went in and asked the workers in English if they used the water and he finally understood and said yes. I should have asked in Spanish. 🙂 It looked good within 4lbs before work, hopefully all is fine.
The living room drywall is almost complete. The parents closet is done and they were working on the parents bath.
