My curly lipstick plant (aeschynanthus) has some pale areas on some leaves, and I have seen it slowly show up on more leaves. The plant is otherwise happy! No direct sunlight, bright indirect next to a window, custom soil mixture for epiphytes, RO water every 3 weeks or so depending on how fast the soil loses moisture. No pests! The only thing I can think of is a nutrient deficiency or a pH issue. I love this plant, don’t want to accidentally kill it. Not getting consistent diagnosis using app AI. I’ve had this plant for over a year, been in current pot for about 12 months. Any help really appreciated!
