Hey everyone I noticed these brown spots on a few leaves any idea what it could be. I have not been supplying nutrients and I do not know the PH of the soil. The plant has 3 CCFL's and is getting constant airflow. Any help would be appreciated. [img=http://img413.imageshack.us/img413/6598/1002880jx7.th.jpg]
Two mistakes 1. not supplying it with nutrients and 2. not knowing the pH. It looks almost like a boron deficiency which is rare [I have never seen it here on the boards that I recall] or it is some kind of mold/fungus.
