Hi all, firstly thanks so much for the help on my previous post (which, for additional information, was almost two weeks ago and was asking about thrips). This will be a long-ish read but I would really like to provide as much information as possible for you all! I had been convinced that the cause to my string of hearts dropping a lot of leaves was thrips, as I found lots of black dots on the underside of some of the leaves and thought I had even seen one itself. But I am having second thoughts. Since then I sprayed the plant with a mixture of neem oil, water, and castile soap (which contained natural peppermint oil) as advised. It’s only been two weeks, but I have no longer seen the black dots or any bugs themselves. However, my plant has rapidly declined in health - and dropped pretty much all its leaves (some of which have been photographed below). The leaves it drops have slightly translucent patches, which are often crinkled, and the underside of the leaves (and it can’t be slightly seen on the top of the leaves too) have turned a dull grey as seen in the picture. In terms of light, this plant is hanging in front of a south-facing window. My country doesn’t get much light in the winter so I keep it there in hopes of getting as much light as possible on the few sunny days. I am hoping to add a grow light to all my plants soon. In terms of watering, I have not watered it in over a month as the soil has not dried out yet. When I last watered it, I let it soak up water from the bottom. It did seem to be slightly overwatered which is why I’m letting it dry out. I would have expected it not to be overwatered still - currently, it is dry on the top and damp underneath (but not wet). Its roots look healthy as well and there are no signs of root rot. I was wondering if anyone has any idea what could be the problem, and what I can do to help? If you need any more information let me know. Thank you!
