Apoptosis/senescence is the first thing that comes to mind after 5 months, but if they didn't get a winter rest in cold temps, it will definitely have a negative effect on how they perform indoors, too. They won't like being deprived of a dormancy at all.

let them go dormant for a few months. expose them to codler temps and maybe you can store them in the fridge/freezer for a while? they do need a rest period. why do grow them indoors? maybe you can limp it alonguntil this fall, then bury the pot in the ground for winter.
