ya if a plants growth stunts is it still capable of getting its maximum yield or will it never be able to get as much as it could of with out the growth stunt
I wouldn't put a sick plant into bloom without righting it first.
Plants are normally stunted from overwatering or overfeeding.
You can't expect a sick plant to perform at it's highest level.
A plant that had issues is unlikely to be as good as a healthy one. Also while your waiting hoping that it will come back you could have started new ones.
