Hi everyone, I'm really hoping someone can help me out! I've recently been struggling with fungus gnats (and possibly thrips or spider mites too but I'm not entirely sure) on a lot of my house plants. I have been using some pesticide spray and was wiping the leaves of my plants most days. It seems most of them have recovered but my favourite Calathea 'Beauty Star' seems to be struggling - the leaves are curling one at a time and then turn yellow and die. I've tried bottom watering and misting, and it's not kept in direct sunlight either. I use tap water that's been left to stand for several days or rain water if I can collect some. I'm really not sure what to do or how to help it?!
