This pepper plant is ill?

The leaves of this pepper plant went funny

It's growing in a growbag in the greenhouse. 2 plants to a growbag, the other one hasn't any problems.

Does anyone know what's wrong with this one and what can I do to cure it? Thanks in advance.

 

I'm thinking Red Spider Mite. Not sure if there's any effective treatment. Others might be able to help/advise.

 

I dunno what it is, but my thoughts are, its not red spider.
Usually, to have that kind of damage, red spider would be producing webbing.

Something? is attacking the growing point, and the leaves are growing deformed and discoloured as a result.
I'd just give it a squirt with insecticide and hope for fresh growth.

 

I tend to have spider mite in the greenhouse a bit later, and they usually go for cucumbers and aubergines and do not damage to peppers. But Freddy's suggestion does put me on alert.

I didn't see any webs on the plant, just leaves discoloured and some dropping off. I was wondering if it is some kind of fungal problem?

 

It's just those distorted/stunted leaves that make me think RSM. Something has had a go at it, and Greenfly would be the first thing I'd look for. I'm assuming you've already checked for that, hence my suggestion, but yes, Pete is right about the webbing. Worth a close inspection.

 

Since my last post here, I've been doing as @Freddy suggested, armed with a magnifying glass and checking on webs of spider mite. And I'm glad to say that I have found no sign of them.

I didn't spray it with any pesticide or fungicide, but did give it a seaweed feed. 10 days have passed, this is what the plant is looking now

It has put on a bit of new growth, and there is no further discolouration. Let us hope that it has shrugged off whatever was there and will continue to grow happily ever after.

Thank you Freddy and @pete.

 

Looking good @HsuH
