Hi all- it has been a while since I've posted but I now have a very sad looking mini. It is potted and sitting on my windowsill at work where it gets lots of sun. It has been blooming but the leaves turn yellow/green yet the veins remain dark green and sometimes get GREEN spots- they fall off very easily. Some of the leaves have the leaf tips brown. I did not see any spider mites. It is growing new leaves. I am watering it when the top soil gets slightly dry...Any suggestions?
