I am having trouble with my marijuana plant, it has yellowing dry leaves and leaf tip s on alot of the fan leaves and smaller leaves around the growth nodes..the plant is a month and three weeks old and started having problems about two weeks ago and I have had this problem before with past plants and have been wanting input on the problem... I had the plant under a150w cfl for a short time but that light burnt out so I was forced to switch the plant to a 15w cfl..the plant was also recently transplanted and I always use fox farms in my pots and I use micro nutrients and I alsohave a nutrient schedual for it but as soon as the problem arose I cut its feedings down. all the pictures I have included are of the same plant and the yellowing is all overt the plant..please post input..greatly appreciated:]
