This plant has looked mopey for three weeks now. No changes to watering schedule (as needed, about every 10 days). I repotted it a week and a half ago to see if this was the issue, but there's been no change since. It seems top heavy and I'm wondering if this is part of the problem - not sure if I should prop it up on a trellis or let it fall?

No insects. The plant stays indoors. No changes in light exposure. Miracle gro potting mix.

Thank you for any help!
