Hello, I am having a problem with my curry plant. It started last week. Some of the leaves are turning brown on the tips. Some entire branches have leaves that are turning yellow falling off, seems to be the lower branches are falling off first. Some seem to stay green but are dropping off from the trunk first towards the tip. The bigger of my plants have lost roughly 30% of it's branches and leaves and the smaller is starting down the same path but seems be be fairing better so far. Both are inside plants and have we haven't had real changes in weather. I have been watering them the same. Any suggestions?
