some kind of virus? this is the newest leaf on my philodendron jose buono x pinnatilobum, and none of the other leaves on the plant have similar discoloration. i only noticed it now because the sunlight moved directly behind the plant, and was perplexed that it looked more like a watermelon mosaic virus than the ones i typically see on aroids. no pests on the plant, which has had a very healthy life with me up till now. i water the plant normally, there is no overwatering happening (good lord, figuring out exactly how to phrase this to please the stupid robot almost deterred me from posting at all!). what is going on here?
