Ok I have 4 plants in Flower stage and have been grown 2 months under T5 18/6 and then changed to 12/12 for 2 weeks under the T5. They started budding great. Well 5 days ago change to a 600 watt HPS and built a 4'x4' area and it seems like they stopped doing anything. They look health just no change. Are they just confused and will start growing again?
