I would just rotate the pot.
The flowers will find the sun on their own.
They will grow up towards the sun.
And you will see how it flowers horizontal... for future reference. lol.
Remember it is still healing and you do not want to stress it....lucky you haven't already!
When in flower you just need to let her do her thing.
Only do what is needed. Not what YOU think she should get, only what she needs.
