Hi,

Can you name this problem on my seedling leaves? I saw these white dots on one of them yesterday , now I see them on the seedling next to it.



What can I do about it?

Thanks,

Looks like some kind of contact damage to me. Maybe water with too much salt?

Thanks Skeeter,

They are in a small hobby greenhouse at my balcony.These leaves are touching the side cover plastic and there is always flowing water on the side cover because of vapourization.May this be the problem?

That may explain the problem-- water drops are probably focusing the sunlight on the leaf like a magnifying glass burning spots on the leaf, but only when they stop in one spot for a while.

Try putting a shade cloth over the sunny side of the greenhouse--citrus do not need full strength sunlight.
