I have a Maple bonsai tree and I'm worried that I might have an issue with it based on the looks of the leaves. I just noticed this about two weeks ago thinking I might not be watering it enough! I have had the tree in its current pot for about a year and few months! I'm new to bonsai and have been watching the the threads about not using potting soil and I hate to say but I'm using it! My plan is to repot it next year with a good bonsai soil. But for now I'm concerned about how some of the leaves are starting to turn in and looking like they might be getting to much sun or not enough water. I have also kinda theorized that it might be that my bonsai table is to close to the house and the sun light is reflecting on my house and burning the leaves. The trees get really good sun from sunrise till around 1and than have afternoon shade. I usually water twice a day once in the morning and after work I have been watching when I water to make sure water is going through the drain holes! So if you guys have any thoughts please let me know what you think.
