I have seen that problem before, in the books, can't remember what was the culprit ... but, it's in here: Revised: The Complete Guide To Sick Plants,pH and Pest Troubles - PlanetGanja.com (http://www.planetganja.com/highsociety/showthread.php?t=8778) ... that's a very good 'plant problems' grow-guide ... good luck :jointsmile:
