Yep, that's sunburn. Outdoors, even in shade, is brighter than inside.

I've got a system worked out that does well. For about 1 week (2 weeks on sensitive plants) I leave them on the north side of the house. Shade all day but still bright and they get used to the wind & outdoor humidity, etc.

Then they go to some other side of the house for 1 to 2 weeks where they sit under an oak or bamboo or even under the boat (trailer) for flats of seedlings so that they get shade from 9 or 10 until 3 or 4 but they get direct sun before and/or after those hours. I generally ease them out from under the oak so that their sun hours slowly increase over a week or two.
