Hey guys im almost 8 weeks into my first grow. I have 6 auto flower NYC diesel. They're in fox farm ocean forest. No nutes till the 5th week. On week 5, I started slowly with fox farm grow big. That's when I started to notice the Browning. It's progressively gotten worse since then. I've tried diatomaceous earth because I read fox farm comes with pests. All water has been thru a filter and ph'd to 6 to 6.5. Light schedule is 20/4 with 2 Marshydro300 and 1 600. Temperature is 75 to 80. Humidity is 40 to 50. I can't figure out what the hell this one plants problem is. The rest seem ok to me. Please help! Thanks
