What is this ?

It only seems to be on 1 leaf and a few tiny patches on a couple of others,its looks kind of see through like spit or somthing.
I checked under the leaf and didnt see anything crawling about and on other leaves too.

That happens to mine when I spray water and it dries on the leaves

Ok thanks,but i havnt sprayed anything on the leaves and they have never tasted rain water

Lol, you got thrips. Hell, most of us have mites this time of year. Use a product containing spinosad to get rid of em. You can also put it next to some bushes/tall grass/weeds where you've seen ladybugs. They eat em.

i agree. looks like thrips. spinosad works well. GL

what they said...

Just a guess but could be leaf miners.

I found a couple of tiny little green things running on the top of leaves.. fast little buggers are these thrips ?
I've read you can use washing up liquid mixed with water to spray the leaves and stems but plant is flowering big time so i guess i should avoid the buds ?
I live in the UK and not sure i can get hold of this spinosad stuff.
