continuous harevest

i have harvested the top half of my plants, but the lower half were pretty small. question is by putting these back under 12/12 cycle, will the baby buds still grow in size or is plant done?

probably shocked for the first week, but they will grow

thanks for the quick reply. this is my first grow and should of lst the plants and put into 12/12 cycle earlier. I waited until Icould afford a 400 watt hps. i got 5 plants top halfs drying, and put 4 back under the lights. I am just giving water now, but should I feed or continue straight water to flush out. By the way, they are in soil.
