Don't pick anymore flowers, they represent new growth. You are still producing bud-like growth because it really takes some time to revert back to veg. I don't usually suggest 24/7 lighting but I have seen great success come from re-veging this way. Turn the lights on 24/7 but don't be surprised if you still have tiny buds trying to form, it will probably show pre-flowers the whole growth now. After new growth begins to show, turn the lights back 18/6 and watch em grow, again lol.
