Hi guys!! I have a lipstick plant that was doing really well, but I noticed that the new leaves growing on them have these really weird yellow spots on them. It's not on any of the older leaves - just the new ones! I was scared it might be thrips or other pests but I did multiple, very thorough checks and there are no pests anywhere, including on my other plants. I switched to bottom watering recently because I wondered if maybe it was being underwatered? Otherwise I have no clue what to do about this or if it means the plant is unhappy :( any help or advice would be greatly appreciated!!!
