Ask a Question forum: Why are my cucumber seedlings curling up and turning white

About a month ago I started my plants in those jiffy greenhouses and they were doing great. About a week and a half ago ( before I knew otherwise) I transplanted them into bigger containers because the roots we're getting out of hand and decided to leave them outside to get some sun. It very soon got colder (around +10°c) And forgot about them for a few hours. They started turning white and curling up. They started getting better a few days ago and grew some new leaves. But now it looks like they've taken a turn for the worst. Will they be okay?

The secondary leaves (the ones that look like little tiny cucumber leaves) look good. The primary leaves (the round ones) don't really count.

As Daisy said, as long as the new leaves are OK they'll be fine. The first leaves most likely got sunburnt when they were out in the sun for too long when they weren't used to being outdoors. They need to be introduced to the sun gradually even from a greenhouse.
