Intense root growth during flowering

[Billentus]

hi,
i just transplanted my auto which has just started flowering, Turned her over to a 3 gal pot. the roots however have started to pop out of the drainage holes again, can it be getting rootbound in a 3 gallon pot? and how much root growth occurs during the beginning of flowering? should i go ahead and transplant them, the roots are looking thick so what should i do. i don't have time for it to recover from any stress so i cnt have any damage.

Thanks.

Best to leave it, roots sticking out the bottom do not mean she is rootbound, there is explosive root growth at the start of flowering
