Warping chilli leaf

[Marb67]

Well, this is an absolute mystery as there are no aphids on the plants but eat all my chilli's and other peppers gave strange distorted, bubbling, twisted leaf patterns on greenhouse and outside plants.

I get that every now and again, too. I don't know what causes it, but I've never known it to do any harm to the plant, so I just ignore it. I suggest you do the same.

If I had to take a guess at what is causing it, I would imagine the leaf sustained some sort of damage when it was still very small. This damage then healed, but that scar tissue prevented the leaf from expanding properly, hence the distorted shape.
