Spinach & Swiss Chard - Sunburned leaves? OR???

Can anyone tell me what's going on with my spinach and swiss chard? Several of the leaves look almost as though they've been sunburned with dry, whitish discoloration on the leaves (see pics below). Only thing is we haven't had much in the way of sun yet this spring, except one little period where temps here in Seattle were close to normal (65 or so). Do spinach and swiss chard sunburn? Or what else could be causing this? Thanks!

could be fertilizer burn or wind burn. Need more information about conditions before making a better guess.

Detach a leaf, then hold it up to the light and look at the edges of the pale area. Likely you'll find some small critters still inside the leaf. They feed between the upper & lower layers of the leaf.

Are those pics of seedlings still in flats? If so, the problem may go away when the plants are set out. It's easy for plants to be unhealthy in some way when growing in the restricted conditions of a flat.

I had that happen with my chard last year, with full grown healthy plants. It was only a few leaves, so I just picked them off and threw them away. I think it was bugs, and I didn't lose any plants from it. It looked exactly like that.

Thanks jean001! Sure enough, leaf miners. Many have since moved on, but found several still in there hanging out. Removed all the affected leaves. Any organic way to prevent them?
