Pepper plant problem

Sorry I can't give a picture as I haven't seen the plant in question (it belongs to one of the daughters 200 miles away) and since I don't grow peppers, I'm asking for some help.

She has 2 pepper plants growing on a very sunny window-sill. They are each in their own 7" or 8" pot (she's not sure which!) and each plant is about 15" - 17" high. To all intents and purposes they are healthy with plenty of bright green leaves but .... some of the upper leaves on one plant (the one which has just begun to produce flowers) have begun to curl, although they remain bright green and show no sign of wilting, drooping or dropping off. She's looked all over the plant for any signs of 'bugs, flies or creepy-crawlies', but can find nothing.

She's not really concerned about a 'crop' as such, since she's grown these basically for fun, as house plants and if she gets peppers it will just be a bonus, but can anyone please tell me if this is a common problem? Is there something she should or shouldn't do with the plant, pick off the 'infected' leaves for example? And will it spread to the other plant?

Any assistance would be greatly appreciated.

 

Hi Fidgetsmum

You say very sunny ,is it possibly leaf scorch

 

Thanks for the replies.

She's sent a pic to my mobile and it's definitely not sun scorch. There are no marks or patches on the leaves and in fact they don't really look any different from any of the other leaves except ... well, I suppose the best way I can describe it is that the affected leaves, rather than being smooth, have lots of little raised patches over the surface and are curling in on themselves. She's also sent me a close-up, and it's not a leaf miner nor are there any signs of any type of 'infestation'.

If anyone does have any other thoughts, please do tell. I'll try and get her to email me a pic then I can put it up.

 

If she can manage it, the spider mite doesn't like high humidity? If she can create an environment with high humidity that MAY help the situation.
