I just got my very first 2 dwarf lemon trees and I'm having some concerns on one of them. I keep them both by the window where it gets about 6 hours of sunlight during the day and I keep it under a florescent light for another 6-8 hours after sundown. I hand pollinate daily and keep a humidifier nearby to keep them from drying up.

All of a sudden, I'm noticing very droopy leaves on one. This started right after I watered it for the first time after bringing it home. The droopy leaves are mostly at the top (for now) and I'm also noticing the flowers wilting away as well... The leaves towards the bottom are very healthy. I'm so confused...

The other one is doing perfectly fine and I'm taking care of both exactly the same.

Can anyone help with suggestions??

Thank you!
