Did the silvery leaves occur when placed outside? I ask because, I put out some peppers direct morning sun after they were under lights and the leaves got burnt a silvery white color. If that's the case need to harden them off by slowly introducing them to the sun. Maybe put them under a tree to get speckled sun then morning sun for a few hours etc.

If this is not the case could you post a pic so we can see

Yes, it sounds like sunburn to me too. That is assuming the plants were just recently put outside.

If so, you will want to get them out of the direct sunlight right away, put them in a shaded spot for a couple days. Then slowly move them back to where they get more and more direct sun each day. Increase the sun exposure on a couple more hours every two days or so.

The damage is done if they already have sunburn and it will likely cause the plant to lose some leaves. Usually the older leaves lower down are the most affected. If they fall off, no big deal. Chances are the plant won't be negatively affected much if at all unless you really fried the poor things.

As Hajolokia said, a picture would help immensely.

Silvery leaves sounds wrong. Here's a pic of tobasco leaves on a plant I grew indoors last winter. I'd call them shiny, not silvery.

Here is what some sunburn looks like with the silver color, I then put them under a tree to prevent more damage then slowly introduced them to the sun, the affected leaves fell off and new ones grew. They are now big and healthy with pods.

it is possible they got a bit sunburned, but that was 3 weeks ago. It seemed they were a bit silvery under lights also....always a bit different.......and yes, i have definitely sunburned some leaves in the past....but i don't think this is the case.......camera broken...no skullular phone either...not a modern man

i will wait and see in a 2 or 3 weeks and let you know the progress......thanks for the suggestions----bob
