What's wrong with my pepper plant?

[Jimmy]

I have 3 Corno Rosso pepper plants in a grow bag.
They were doing OK but the left one now has strange leaf.
Anyone any idea what it might be and what a cure may be?
See pic.
Thanks Jimmy

looks OK to me - bit of mechanical damage perhaps

Are there any small aphids under the leaves,it looks like the plant next to it has its new growth affected too?

[mrbadexample]

Aphids, without a doubt.

Definitely looks like aphids to me too..check the underside of the the crinkled leaves.

Though sometimes the crinkles leaves can be a sign of overwatering but the one on the left looks strange. Get a magnifying glass out

[Jungle Jane]

Drainage is difficult in a grow bag,could be overwatering or aphid,poke lots of holes around the edge & corners. Holes on the bottom of the bag sometimes get blocked/lack of air within the bag.

Thanks will investigate.
Does soapy water deter them?

I always use a small pencil torch to shine up through the leaves as i look down. Makes it really easy to spot any issues. Anything black gets picked off the leaf just to be safe. Baggy sacs of fluid are kind of obvious done this way.

Garlic infused soapy water deters more because of the smell,spraying needs repeating every other day unless you have ladybirds around. It’s best to spray the plants in the evening when the suns gone down.
