White Diesel Haze auto 1st grow

Switched to flowering lights (150W HPS) this week following signs of pre-flowering. Defoliated the bottom of the plant by removing the leaves which do not get much light. Growing in general seems to have slowed down, is not agressive as 1-2 weeks ago. Continuing LST by pulling the long branches to the sides of the grow tent to maximise the use of the little surface that is available. Would have done better with a larger tent, even for one plant. Following nutrient schedule proposed by the nute manufacturer (General Hydroponics)
