could be. sometimes leaves will turn yellowish/brown if too close to a light and they get burnt. but ive gotten that same look from cfl's being too close. its just the pattern looks wierd to be from heat.Anyone think it could be due to the light being too close? ........ It only got like that when I put it indoor and the light was a little close (20,000 lumen CFL) 1.5-2 inch proximity :O
