Ive had an open brain for only 2 days. Yesterday I noticed that during the day when the lights are on it gets this brown coloration toward the inside. The brain is green, and some of that green is going away.. I have T5 lighting so I dont think that its getting too much light. Here are a few pics of the first day I got it, and pics I just took a few minutes ago. In the pics that I took today there is less brown shown, than there actually is. What could be causing this?
