I acquired this Bonsai as an Xmas present, so I've had it for several months now. I originally placed it on the windowsill, but it seemed to be drying up quite quickly so I moved it. However, as you can see from the pictures some of the leaves are browning at the tips. Is this just a product of its new location(i.e. it's not getting as much light)? If so, should I just move it again,or is there anything else I can do to remedy this?
