Here's the deal, About 3 weeks ago, I went in to flower from a 250w MH and 96 watts CFL to a 600w HPS with a fan to cool everything down. With the lights on, I'm between 65 and 80 degrees. When the lights go out, it has gotten to the low 40s. I was dealing with powder mildew using hydrogen peroxide and I have since put in a 200 watt heater to help deal with the lights off temps. It now only gets to 59 degrees with lights off.
It the yellowing because of the low temps for a short week? Did the peroxide bleach the leafs? Or is this a nute issue? The plants are Granddaddy purple grown in soil using miracle grow nute for tomato. they get nutes once a week, and water every 2 to 3 days. Here are some pics to help you help me.
