I switched my Super Lemon Haze from 18/6 MH to 12/12 HPS about 2.5-3 weeks ago. I thought that they would be well on their way to flowering but they havent even started! I've been giving them Fox Farms Open Sesame (+ Tiger Bloom) every other watering too. Is this normal? is there anything i can do to maybe "shock" them into flowering like 8/16 or 6/18 lighting?
