HELP! Beetle grubs ate the roots of my mother plant in flower.

[Victory7]

My flowering Blue Dream mother plant in a 5 gal pot got beetle grubs in the roots and ate all the little roots. We got the grubs out and put the plant in rapid root grow and stabilizer for a couple of days then repotted it. I've been taking off the dead leaves and want the opinion from anyone that has been through this as to what to do next.
