More Transplant Issues

[durandal]

So, I started about 2000 transplants all told...half of them were various tomatoes and the rest peppers.

Its my first year growing for market and I wanted to see what I could do.

Anyways, I have several trays that have younger transplants (1 set true leaves) that have gone shade of grey on me in a single day.

Is this sun scalding or something? I just put them out in the full sun for the first time.

It was also fairly breezy.

This was a couple weeks ago. SOme have died and some have hung on and continued to grow.

Anyone know what happened?

I need to get a good handle on what my expected losses are from seed to plant in large numbers so I can plan next year.

Any help would be much appreciated.

looks like sunscald to me. It often happens if their first day out is too long. On a cloudy day, it doesn't matter, but whit sun, I give them15 minutes then 20, then 30...then more and more. Direct sunlight coupled with wind is a killer, especially at that stage. Those who survive often aren't good producers if they have been too burned, it is better to start over. When it happens and I feel they have not been too affected, I replant them deep, letting the last leaves only above the soil. The plants go into root production mode and then burst into solid growth. I leave them in indirect light for a while...

Cloudy days are always best to set them out, always.
