You most likely need to reveg it unless it has alot of leafy green growth on it still..some people multi harvest some strains like "Flo" over a period of time but in most cases it goes - veg flower, reveg, flower

In order to reveg successfully I would transplant the plant if in soil to a new bigger container and give it some Nitrogen rich veg fertilizer and 24 hours of light. The plant may very well be stunted at first and not know what to do and the first new growth will be possibly mutated and wierd. It may even grow male flowers because of the stress. Just pick those off if it does and don't let them open up. Once the plant has grown sufficient new vegetative shoots and leaves then you can reflower it again but expect a lower yield the second time around. Another thing you could do is reveg it and then take clones and grow them out. Hope this helps! :jointsmile: :thumbsup:
