Hello everyone, Although I have some experience growing plants in tropical climates (specially outdoor), since I have moved to Canada, it has been a huge challenge to grow plants indoor. My goal is to grow a plant from seed (misho) and turn it into a small bonsai (shohin) or at least a pre-bonsai. In order to get used with my new environment I have decided to start on herbs, and after reading a book about edible bonsai, I have chosen Rosemary to give a try. I have sown them on June 23rd, 2013, but recently, the leaves of one of my specimen have become brownish and crispy as it can be seen in of the attached pictures. All of them have been raised exactly in the same way and I have also attached a picture of another specimen which seems not to have the same problem. I would need some help to identify what could be the source of this problem. I discarded over-watering as the leaves are not smooth or heavy. I suspect it might be low humidity or under watering. The fact that the seasons in Canada are so different in terms of light, dryness and temperature still makes me unsure of how much and which changes do I need to do. Thanks for you time,
