So this would be my first and hopefully last post. My plants are 2 weeks into veg stage. There are 17 total plants and about 7 of them have started to turn yellow. Same soil , same water in all. Ph of my water is 7. The plants are under 2 400 watt mh and I'm watering every 3 days. Temperature ranges from 70-85*. I have good air movement but no real fresh air coming in. I need as much heat as I can get without having to run the heater too much. Although there is about 15 feet of empty space where ouside air comes in.
