Week 1 flower. Following the nutrient schedule I added .25 tsp of Humboldt nutrients Big Up powder to the water for week one. I watered on 6/19 and went on vacation till 6/23 and I was blown away by the growth in that short period of time. I have also been increasing the intensity of the light by about 50 watts per week. I'm now pulling about 400 watts of light. I'm aiming to have the light at the full 600 watts by the end of week 4 flower.
