Leaves turning pale yellowish white

[Dx916]

First time container grow in miracle grow potting soil. Plants badly wilted when transferred outside and some leaves turned white from sun burn plants but seem to recover and get use to it well.

But now some leaves also seem to be fading which I believe is caused by something else besides the sun/wind? Since taking these pictures I fed them for the first time some 18-18-21 tomato plant food and the new growth is growing in a dark green should I be ok??

The damage in the first two pics I'm sure was the jump from indoor light and temp to 90 degree sunlight, the second two pics is whats in question as far as a cause.
