Hi, I have a small challenge with a Fiddle Leaf Ficus. We delivered the plant approximately 4 month ago to one of our clients. Overall, the plant was and is beautiful, the roots grow strong and are healthy, there is no evidence of pests. We use a special Ion-Exchange Fertilizer which is specially mixed to the soft water here in Vancouver. So the nutrient level is very consistent which I verified by checking the PPM and pH values. For the last four month, the plant was doing great, however approximately 2 weeks ago it started to loose some leafs. Overall the plant still looks very health, except single leafs which eventually fall off. I attached some pictures of the overall tree and one of the leafs which came off. The only thing I can thing off is insufficient lighting. We moved the plant to a brighter spot and I may install a temporary grow light. What else could it be? Any suggestions or ideas? :). Thanks!!!!!
