I have a Tillie Hughes that's been doing great until just recently. Her background...not sure if seedling or propagation, bought from an Etsy seller a few months back, came with healthy roots and no leaves, potted in C&S soil mixed with lots of perlite. Pretty bent over but we're working on getting her straighter. She sits right beside a window which is why her leaves go to one side instead of out like normal. Gets watered about once a week or when a skewer in the soil comes out dry. Now that its finally warm here in MN I went to take her outside yesterday and noticed her leaves have this odd coloring on them. I did see some tiny bugs on her but confused since there's no webbing or white fuzz like spider mites or mealies would indicate. I gave her a good rinse yesterday and today and will apply neem oil as well but has anyone seen this before? Bugs? Sunburn from sitting by the window? Something else? One of the newer leaves has started turning black at the tip as well (last pic). Is this related or possibly from moving her outside into the heat and a bit more sun than she's been getting? Thanks for any help and for reading my short novel!
